Title: Tether Flying for S&T models
Post by thymekiller on May 6th, 2010 at 11:43am
There has been some really great info on c/l flying posted lately. Thanks for that. It makes me want to try it. Also, I have to admit to an intrest in tether flying. Thought I would start this thread so that I dont hijack any others.
Anybody ever done any tether flying? Rubber power or otherwise? I thought I might try it on maybe a 15 foot lead, with an old cessna that I dont mind crashing. ;D
Do I lead the plane alittle bit or just hold on and let it go on its own? What about just letting it go around while being attached to a swivel?
I have seen pics of this but the flyer held on to a stick, attached to the lead.
One of many things I like about this hobby is that there are so many ways to enjoy it.

There are two basic types of tether flying: 1) the airplane is tethered to a swivel attached to a post and allowed to fly freely in a circle. 2) The old, original "whip" method where you're pulling the airplane around on a tether.

With the first type it had better be a really calm day so the airplane stays taut on the tether.

With the second type it's best accomplished with a pole that has the tether line attached (like a fishing pole) so you have something rigid to transfer the energy out nearer to the airplane. Otherwise you'll wind up just wrapping yourself with the tether line.

There probably isn't enough power in rubber power to drag a heavy line through the air with any efficiency. Being as light as rubber powered aircraft are some strong thread will probably work okay if kept fairly short.

Unless you're indoors Mother Nature is gonna try and have her way. She'll treat you like the Wicked Witch of the East would: "I'll get you and your little airplane, too!"

Truly, I can see the fun in both types.  Thanks.  Might try one soon.
Like a rock in a sling? No prop, heavy outer wing tip? Faster you sling it, the higher it flyies? I can see that.

Got an old LOOONG fly fishing rod in a corner somewhere in the shop.
Put a bolt on the end of a 10 ft line and try it.

When I was a kid, my generally non-modeling buddy used to surprise me, occasionaly. He once brought over a small stick model he had constructed of balsa sheet. It had about a 12" span and a stick fuselage, sheet tail feathers. He had tied a string onto one wing and whipped it around on a 10ft line.  It flew pretty good, so I made one as well. For several days afterward we both made a bunch of quick models and had all kinds of fun, shooting carrier landings and some mild aerobatics. We learned the importance of decalage and other trimming methods to obtain the type of flight we wanted. I don't remember getting dizzy, bu t I was probably already a cl flyer at that time.

About 4-5 yrslater, in HS I found a Muciano book in the school library and built the 1/2A Saber Jet  from one of the many plans (IIRC, Walter Muciano's designs formed the basis for most of the old Scientific Kit line). My younger brother had a brand new Cox Baby Bee, so we put it on my 18"Saber and flew it without control from a pole driven into the front lawn. About a 15' braided fishing line was attached directly to the hardwood bellcrank mount button. We had to hand launch it but it never flew into the ground nor started high/low occilations, my main concerns. It flew level with the top of the pole, about three ft tall. For all intents and purposes it was like running a Cox Prop Rod. The pole proved to be the weak link, as it soon developed an insecure status. Later I converted the model to it's original Cl and believe my brother learned to fly it.

Hey guys,

I have a copy of the plans (and the attached construction article) for a Republic F-84G whip control model. Published in American Aircraft Modeler July 1970 magazine. Designed by Joe Wagner (of DAKOTA fame). You use a fishing pole and a control line handle. Built just like a regular control line plane without the engine. Would anyone like a copy?

IIRC, there was an article in an old American Modeler  (mid 1960's?)magazine that showed another type of tether flying. It was called "pole-line",  where a rather long bamboo pole was used to pull a model in a circular flight path. It utilized a rather short line(approx 5'), and instead of attaching to a wing etc., the line clipped to a loop on a free wheeling propeller shaft, to the pole tip. Models were lighter than normal control line types. More intune to rubber FF scale.  I tried with an all sheet Piper Vagabond, I'd built for rubbe.r,  bu t didn't like the way the model looked as it flew around the circle. Always seemed to be angled too much toward me. I suspect it was centrifigal force. I believe the article decribed weighing the outside wing to make the model track level. It didnt work for me and soon abandoned the effort.

In the late 60's/early 70's American Modeler became the AMA publication Model Aviation. Another type of tether flying article appeared about that time. It was an .049 glider (of FF inspired R/c type) of about 5' span. A monofiliment fishing line  was attached to one wing tip. With the model trimmed to moderately climb straight out, a spinning reel and pole allowed launch and payout of line. By slowing line  payout a gentle turn could be initiated and when headed back to pilot position, the line taken back in. I suspect that ground snags were a real worry. like the pole line efforts, it never seemed to catch on.

Thanks, Eric, for the kind comments about our experiences with tether aka swing control models and for posting the link to the thread at SFA.

Since the SFA is temporarily down, we will share some updates about our swing control models.

We first flew these as a youngster and a few years ago we became reacquainted with them and have continued to pursue this interest.

A summary of these earlier experiences may be found here:

To date, our favorite swing control model has been the CloudBuster and its current evolution.

It began as a kit built Guillows CloudBusted intended for backyard flying with rubber power.

Thanks, Eric, for your comments.  The single nose wheel was for making touch-and-goes on the small slab at the back door that serves as the porch.  In our current swingers we have omitted the wheels as most of our landings are in the grass.

Frequent flying affords us the opportunity the capture some interesting cloudscapes for the background of our swingers in flight.

The second CloudBuster was a kit-bashed one, using only the wing and fuselage stick from the kit.  The wings were shortened by one bay and the  the tail surfaces were reduced in size.  The wing center section was well reinforced and fitted to allow a removable wing.

That's all it takes, plus some strong line.  I use old half-A U-control nylon line that is in our 'stash' from when we used to fly U-control many years ago.

The pic below shows the steps in our 'learning curve' prior to our first successful flight with a Guillows Trainer 2.  Before the larger models shown we had tried a Walker Firebaby, a Joy products Pee Wee Pup, and a Musciano designed profile P-51, all half-A powered and all crashed.

Right.  We received one for Christmas as a youngster.  We tried to make our first flights from a bare spot in the farmyard next to our home.  On takeoff the lines would snag tall grass causing the model to crash.  After a number of attempts it was badly damaged before a successful flight could be completed:(

Post by simpleflyer on Mar 15th, 2012 at 8:59pm
I guess I should wrap up the story of our successful entry into control line flying.  In the picture a few posts back we were holding a stunt trainer model called the Hound Dog.  Below is an image of the model plan for the HD.  We promptly crashed the Hound Dog as we had crashed one a couple models prior.

After the second HD crash, we had the good fortune of meeting our CL mentor Gerald Jeansonne.  He and his wife ran a local mom & pop hobby shop.  He would often be a the local Cl flying field teaching new CL modelers how to get started with the Guillows trainer 2. After a couple of successful flights with Gerald's trainer we bought and built one and began to fly the wings of that puppy.  We flew it evey opportunity we could and developed our CL abilities. 

Below the Hound Dog is a blurry pic of our old trainer 2.

And below that is a clearer pic of the trainer 2.  Guillows suggested a .19 engine, but Gerald and I used tired old Fox .35s  The bigger engine gave it a bit more speed, but the model felt more secure at the end of the lines with the Fox and could be flown in windy weather.

The next pic is part of model fleet at that time.  Mostly CL models with one simple FF.  This was about 1957.

Title: Re: Tether Flying for S&T models
Post by simpleflyer on Mar 17th, 2012 at 11:25pm
Only the wings of the laser-cut CloudBuster and FlyBoy were built and they went together easily and the laser-cutting was very well done in my opinion.

In addition, we have built the laser-cut Guillows Wright Flyer.  We have always been fascinated by this aircraft and its builders the Wright brothers, so we decided to build one a few years ago.  The kit was in my opinion very well done and it went together very well.  It is the most complex model that I have built to date, but it was a model that I had to build.  More pics of the model build can be seen at the 'virtual aerodrome' link at the bottom of this message.  When  you get to our VA hangar, click on  the picture of the Wright Flyer.

A while back we built a Guillows Javelin and converted it for tether flying.  We made it with removable wing and tail surfaces.  Initially they were held on with rubber bands.  Later the wing was changed and held on with magnets and the tail was a slide-on mount.  The Javelin is a fine tether flying model which we fly regularly.

Seems that it has become quiet on the tether flying page.  So, I guess it is time to liven it up a bit.  Since March, we've built a  couple of small 'swingers' of about 12 inches wingspan.  We will post a bit about our work with these little aircraft. 

First we will post a few more pix of the Javelin.  Eric, you may find some of this interesting. 

The first is the Javelin flying in the company of a F-105F Wild-Weasel.  This aircraft is on display at the 23rd Fighter Group Memorial at England Airpark in Alexandria, LA.  England Airpark used to be England Air Force Base which was shut down in Sep 1992.  Now it serves as the commercial airport for Alexandria.

Tne next 2 are of the 23rds group emblem.

The last is a pic of all the aircraft on display:  F-86 Sabre,  A7D Corsair II, A-10 Wart Hog, F-105F, and F-84F Thunderstreak.  All of the aircraft were flown by the 23rd except the F-84F and all were flown at EAFB over the years. 

We have a special attachment for the F-105, in that in 1962 we spent 40 weeks at an AF school learning the weapons control system on this bird, only to be assigned to an Air Base in Japan to work on the F-100 for the rest of our short stay in the AF.  The ways of the military sometimes work in mysterious ways :-?  There is also an attachment for the F-100, gut that story is for later.

Ok, here is the 'tiny swingers' fleet when it started around 2009.  These were a study of tiny simple airplanes that could be flown, simply, easily, and cheaply.

The two models in the upper left corner are simple gliders folded from paper and flown on a piece of thread. 

The illustration shows how easily this can be accomplished.

Your question started me to thinking.  I looked up at our ceiling fan and wondered, can one fly some 'swingers' with it.  Even at low speed the blades were rotating at a good clip.  At the same time I remembered the 'Pole Line Flyers' by Ken Bale.  The models would have to be small and tough if they were going to be swung by the fan blades.

I remembered that a few years ago we built a number of Fiddlers Green card model airplanes in 1/100 scale.  These ought to be strong, light and small enough to be connected to the fans blades and flown.  So we selected the models in the picture to give it a try.

First we took the F-22 Raptor and attached it to a blade with some tape and a piece of thread and gave it a try.  It went well enough.

So we wiped off the fans blades and added a model to each one with a bit of clear tape and thread.  Flipped on the switch and gave them a whirl.  They are kind of hard to see them as they swing about.  The Kodaks flash stops them in the digital pic but they are kinda tiny

In the group photo posted in msg #51 in the upper right there are some card models that we flew as 'swingers'.  The best flyer was the J-3, the tailless models not so good.  They are all Fiddlers Green card models.

Today we took the three models pictured below for some backyard flights.  The J-3 and the sailplane are Fiddlers Green models.  The B-17 is a Rigby model.  I have a faint recollection of trying to construct one of these as a youngster.

The sailplane is a poor flyer.  The wings are too long and skinny and warped.  How ever it looks good in the flight pic.

The B-17 and the J-3 fly well for being card models.  Looking forward to building them again.  These are cheap and easy flyers.  Many of the digital files for printing these out are free on the internet. 

To build them, all one needs is card stock, Elmers white glue and a pair of sharp scissors.  No additional covering or decorating is needed.  A little nose weight for balancing and a piece of string and a pole and your're ready to fly.

I have been meaning to try Fiddlers Green models.

btw, cool that you have all those jets to look at. What a great place to have lunch or gather with the family.

Soon as I get a ceiling fan hooked up, I may try it myself.  Looks cool in the pic!!! 8-) 8-)

Tom, your comment is appreciated and I'm glad that you  like the models.

Another model in the picture in msg #51 is a small profile model of the Turbo Commander.  Below are a couple pictures of the model.  It is of all sheet construction of about 8 inches wingspan.  The profile swing control models were based on a couple of series of nocal gliders and rubber powered models that Guillows produced in the 1950s.  More information about them is on page 1 of a thread at:

Another model in the group picture is this profile Avia C-10.  It is based on yet another line of Guillows nocals.  these had sheet fuselage and tail with a tissue covered wing.

More info about these models can be found at the end of page 3 and the start of page 4 of the thread at:
http://balsamodels.com/phpBB/viewtopic.php?f=2&t=1646
These models are about 12 inches wingspan and have proven to be fine flyers.

Thanks for the link to guillows...a lot of the models look like they could be converted to catapult launched gliders as well....have built a few of them and they are great fun as well. 
Here's a link to them on HPA: http://www.hippocketaeronautics.com/hpa_forum/index.php/topic,3985.0.html ; under the name Sky9pilot.

Thank you, Tom, for your comment and the link to your catapult gliders.  We checked on the link and looked at your gliders.  They are very colorful and nicely built.

We tinkered a bit with tiny gliders in the backyard.  But their flights tended to the quick and short and if they flew for a longer time they tended to escape the confines of our back yard, so after at time we converted most of them to tether flying.

Some of our results with these as cat gliders may be seen at:

Eric, Just noticed your comment on the title page about the tether models.  Thanks,

A couple of comments on the Turbo Commander model on the previous page.  We became acquainted with the subject aircraft during the 1970s.  Below is a pic of it in 1981, a beautiful and fine flying aircraft.  Also a pic of the pilots.  On the right is Jerry the chief pilot and on the left is Tom the co-pilot.  Tom had flown Hueys in Viet Nam a few years prior and had some amazing experiences to relate.  Both were excellent pilots and generous gentlemen.  They took me for a few rides in N100TT when the opportunity presented itself and no one was looking ;)  On a maintenance check flight, Jerry allowed me a few moments of stick time.  A memory that I tresure to this day.

In the previous page of this thread is a group picture of small and simple to fly tether control models.  The cropped view of that picture below show three scale models of 12 inch or less wingspan.

The Ryan ST at the top is the Comet nickel version of about 11 inches wingspan.  It was modified to have sheet balsa fuselage sides and tail surfaces.

The P-51  on the left is about 13 inches wingspan and designed by Herb Weiss.  It was designed as a stick and tissue model with sheet balsa tail surfaces. We modified it by  changing the fuselage side to sheet balsa as shown in the picture.  It is a good flyer for its small size.

The third model pictured in the previous post is a Stinson 108.  It was a 10 cent Comet kit marketed around 1950 and had a wingspan of 12 inches.  As a youngster, it was one of the first models that we built.

When we returned to model building after retiring, it was our return to stick and tissue models.  Mostly, it was an exercise in nostalgia.  At first, it remained a static model to remind me of some happy times from long ago.

As we experimented with a variety models for tether control flying, the Stinson 108 was tried.  In spite of its small size it has turned out to be a good flyer.

Here are a few of our favorite flight shots.  The last one in the series was taken yesterday.

Coincidentally, after posting the Stinson pix, it suffered some hangar rash when the swing pole fell on the rear fuselage.

At first, we thought we would need to build a new fuselage.  After looking at the damage more closely, it appeared to be repairable without much effort.

One vertical stick was broken and the two upper longerons were cracked in a few places.

With the hot weather these days, we stays indoors a lot so we  had a bit more time to work on the Stinson.

The fuselage was ready for covering, so we replaced the tissue that was prior to making repairs.

Then we applied a coat of thinned white glue to the newly applied tissue.

After the thinned white glue dried, the tail surfaces were reattached to the fuselage.

After a few hours of drying the Stinson was ready for a test flight and it flew as well as before the accident.

Later, we will apply a couple more coats of thinned white glue.  When these have dried, we will spray the newly covered areas with a couple of coats of spray can clear polyurethane.  After the polyurethane hardens, it allows the thinned glue coated tissue to be a bit more agreeable with the humid climate here in south Texas, enableing us to fly in wet and damp conditions.

Cool lawn rats.  I like mine pan fried with white gravy.  :D
Just kidding.   Around here, some folks throw rabbit chow for them.  They get pretty tame pretty quick.  They like vegetable scraps and a pan of water.  Pretty soon, you will have many of them. 

Where I work, there were hundreds which is strange because it's all paved.  We noticed a fairly sudden drop in the visible population and made friends with the reason.

Thank you, Eric, for your comments.  We also like SnT models.  As we mentioned to Tom,  the Stinson was one of our first models and is a sentimental favorite.  For this reason, I try to keep this particular model flying as long as possible.


Quote:

Ditto, this is what we like so much about swing control.  It allows us to fly almost any day that I can get out into the backyard.  Over the years this has allowed us to fly our models with a variety of skyscapes as the background.


Quote:

Ditto again, in a gentler less complex time long ago when rabbit was an acceptable item on the family table we ate rabbit.  Mom did in fact use white gravy as the sauce but broiled the rabbit in a stewpot as sometimes the rabbit was a bit lean and stringy [smiley=thumbsup.gif]

However, I don't recall eating rabbit since those 50 years ago as a child on the family farm.  Since we now live in small town being slowly swallowed by the urban sprawl of southwest Houston; we've turned the parts of our back yard not used for flying or childbride's flowering plants into a mini-refuge for the local wildbirds and furry critters.

That's cool!!  We did that at the old house. Currently, the wife has feeders for just about anything that shows up. Much smaller yard than before.  Makes it easier to maintain.  The only hunting I've done lately is with a camera.

Had rabbit stew just a couple years ago.  There's a person who sometimes sits at the front of the local Walmart entrance and sells excess white rabbits. If theres no kids around, he will wack it for ya' so you don't need a cage. These days you gotta be careful who's around when you do something like that.  ;)  Funny how some folks scream about animal rights, but think nothing about eating a hamburger. I guarantee those home raised meat animals live better than those feed lot cows.

They sell puppies and kitties and such there but I haven't tasted any of them. ;D ;D

Next time the quail guy shows up I might well get a few. Some days it's like a regular petting zoo there.
Every now and again, the Walmart folks halfheartedly run them off, but they come back in a few days.

One of the many blessings I have is I live in a giant small town.  We even have an ordinance that says you can have up to 6 hens in town as long they are caged and you dont have a rooster. 

Title: Re: Tether Flying for S&T models
Post by simpleflyer on Jul 1st, 2012 at 9:14pm
Eric, it is good to read about you and your wife's activities to help the wild critters and your rabbit stories.  We started feeding the birds in the back yard several years ago.  Recently, we've increased this activity by allowing vegetation in parts of  back yard to grow to seed to allow more food and cover for the backyard critters(furry-n-feathered).  By cutting walk ways thru the grass and keeping it clear of the house we are not bothered with the tinier critters trying to move into the house.  The walk ways and clear areas allow the hawk and bigger birds to go after the smaller critters: ie - mice, roaches, snakes, etc.

To turn the topic back to S-n-T, a few days ago I browsed thru some of the comments at SFA about record setting models and it got me to thinking about the R/C electric powered aircraft designed by Paul MacCready and his team.

The most amazing is the Helios.  Think in terms of:  wingspan 247 feet(larger than the B-36, C-5, B.747), 14 electric motors for power, planned eventual flight duration of 6 months per flight, set an altitude record of 96,863 ft for a winged aircraft taking off under its own power.  My hat goes off to Paul MacCready for conning the feds to fund his extraordinary aviation achievements.

One more comment about Paul MacCready.  After reading data at the links posted a couple of messages ago, we wanted to learn more about Paul and his work.

We found the book 'More With Less' written by Paul Ciotti.  It is a quick and easy read.  It presents a lot of interesting information about Paul and his numerous aviation achievements.  Paul was an avid modeler as a youngster and these skills carried over into to full scale aviation efforts.

We got a preowned copy online for about 5 dollars from:

I will try to follow his build and post a few suggestions on his thread and at this thread on how his model could be adapted for swing control.

On this thread, we will explain the rebuild of a 900 series F-51  Mustang that we built a while back.  Below is what is left of it after a lot of flying.  So we are going to 'recycle' it into a profile swing control model [smiley=thumbsup.gif]

Been there, done that.  Some of my first models didn't amount to much.  I was about eleven before taking model building seriously.

Some pix of the Mustang, earlier in its life.

Built for one of KittyFritters Guillows cookups in 2005.  It flew, but not well.  I still had not learned to fly rubber power.  Could fly CL and gliders, but rubber has always eluded me.

So we decided to make it into a swinger.  Pulled out the prop and rubber and replaced it with a glob of clay on the nose.

Flew well as a backyard flyer.

Flying it for ChilBrides nephew and grandnieces at her sisters house in Louisiana.

After a few years and a lot of fuselage damage we junked it and were left with the wing and tail feathers.

We've made some progress with the profile conversion of the Mustang. 

At the upper left are the doublers and reinforcement strips for the nose.  The vertical tail is being glued to the fuselage.

A removable horizontal tail will be used on the model.  Small magnets will hold it in place on the platform which will be glued into the slot at the rear of the fuselage.

Post by simpleflyer on Jul 22nd, 2012 at 2:12am
Tom, the magnets are 1.5 mm dia. and about 1.5 mm long.  They are Neodymium and are available from:
http://www.kjmagnetics.com/categories.asp
An internet buddy, Phil Finn, gave an assortment of these including the tiny ones.  I've ordered additional magnets from K&J.  Their service is good and their prices are OK, especially their sale items.

The small ones will be OK for the Mustang tail since the slot will be doing most of the work of holding the part in place.  The magnets will be there mainly for alignment  and to keep the surface from shifting in flight.

Early on, I used two pairs of the 3mm x 1.5mm magnets in each of the wing mountings of the Javelin and the FlyBoy.  They held the wing securely unless I would jerk the swing line excessively or fly into something in the flight path [smiley=thumbsup.gif]

Post by thymekiller on Jul 23rd, 2012 at 2:40pm
Simpleflyer is correct. When it comes to magnets, just a dab will do it.  GREAT fun to play with!!  Use them in pairs and they are self aligning, almost as good as alignment pegs.
Also, your wing will seperate before breaking, on a tip landing, if you use the correct size. Could have used them on my Ercoupe LG, if I had put in the tinyest effort. {pun intended ;D}

The strength is listed in the "N" number. N52 are dangerous strong and challenging to work with. When your cylinder magnets "find" each other, you need a knife to separate the small ones.  Keep them away from anything with a circuit board. [cell phones, confusers, digital scales, ect] I recommend the "lighter" units. A "N52 1/8 dia x 1/8 thick" will easily hold a 22 ounce framing hammer off the floor. 
They weigh practically nothing, just don't put them directly on the electronic scales!!! 

I was going to post a link to where I get my magnets, but the one posted by Simpleflyer is better. Much more info and many different sizes and shapes. Thanks for the link, Simple flyer. In the future, I see many folks using them as invisible fasteners for wings, cowlings, landing gear, ect.  I have used them on two models and fully plan to make them a fairly regular part of building.

Besides, get a few and they will make you grin while playing with them. 8-) 8-)

The wing frame is finished.  The Guillows two piece wing is changed to a one piece wing with a 1/16 " wide trough at the centerline.  This will allow the wing to be slid into a slot in the profile fuselage.

The nose doublers and reinforcement strips are ready to be glued to the forward fuselage.  This combination give needed weight to the forward fuselage, provides extra strength to the forward fuselage which arrives at a bad landing first ;), and provides a secure mounting for the wing.

Thanks, Tom & Eric for your comments.  We've been sorta busy with domestic chores, so the work on the Mustang has slowed.

So we'll post a few pictures of sheet wood swing control model that we completed a couple of weeks ago.  It is a Douglas A/B-26 that had been converted to a Monarch 26.

These are the latest pix of the model.

If you would like to see the story of the build check this thread at the Guillows forum:

The exhausts were salvaged from the destroyed fuselage that was discarded.  We'll plug along with this Mustang project.  Next we'll cut and apply some racing and registration numbers.  Eventually, we will probably replace the tail with a yellow one.

Completed, the model needed nose weight for stable flight.  A hole was punched in the nose to allow a piece of plastic straw to be inserted.  A small glob of clay was inserted into the end of the straw.  This allows the weight to be adjusted.

Thanks, Tom and Eric for your comments, glad that the nose balancing tip was of use to you.

Our next 'swinger' will be another A-26.  This time it is a 12 inch WS version of N256H, the tri-motor version used for engine tests.

The plan was sketched a few years ago for a rubber powered 'root-canal'  FF model that was never built.  Since the plan was traced from the Comet model it will need a fuselage update.

A picture of simple 'root-canal' model is shown.  There is a thread about them at SFA:

At the time of making the plan we were working from a magazine picture of N256H and the Comet plan for the A-26 shapes.  Since then we've learned a lot about N256H, including the fact that we had seen it in the 1960s before it was acquired by Garrett for the engine tests.

We found a neat profile of N3035S which was later registered as N256H.  The history of the number change is at:
http://napoleon130.tripod.com/id690.html

With a little help from MS paint we were able to insert N3035H into our sketch.

Now all you have to do is print it and stick it on, or something like that.....

Title: Re: Tether Flying for S&T models
Post by simpleflyer on Sep 29th, 2012 at 9:05pm
Eric, that is a good idea about pasting the profile to the balsa.  I've thought something similar in modifying the image by copying and flipping the profile so there would be profiles of both sides of the fuselage.  Then printing the two sides to a piece of tissue or thin tracing paper and gluing it to both sides of the profile.

I haven't yet decided if the wing will be removable or not.  If I go with the removable wing, probably colored marking pens will be used for decorations.  Because of the curious history of this aircraft, we are planning to make different versions of it.  Tom, it should prove to be an interesting build.

To digress a bit, we will share our fortunate opportunity to see N256H/N3035S in real time.

In 1966-1969 we were attending Spartan School of Aero. followed by working in the Spartan engine overhaul shop.  In our spare time, we spent a lot of time browsing around the local airports and taking pictures of airplanes.  Access to the airports to take pictures was much easier in those happier days.

In 1967-68 we had the chance to get some pictures of N-256H/N3035S.  The first two pix are of an OnMark Marketeer with the N256H registration(12-06-67).  The third picture is an OnMark Marksman with the N3035S registration(06-04-68).

Title: Re: Tether Flying for S&T models
Post by simpleflyer on Sep 29th, 2012 at 9:57pm
About a month later(07-03-68), we met the Marketeer wearing the Reg.# N3035S.

A couple of days later we saw the Marksman wearing # N256H and a new paint job parked in front of the Spartan airframe shop.  We were then working at the Spartan engine shop across the street.

In 1971, visiting the Jackson, MS airport we met up  with N256H one last time.  Eight years later, Garrett Corp of Phoenix, AZ acquired the airplane and modified it into flying test bed for turboprop engines.

At the time we took these pix we did not realize what would come of this aircraft in the scheme of things.  It was just one/(two) of a bunch of A-26's we've been blessed with having the opportunity of meeting over many years.  I think we will start an A-26 'bay' at the Hangar section of S-n-T and show some of the other A-26's. 

We'll repeat the links where a more detailed story of this unique bird may be found.

Very nice.  Is that 1/16 balsa?  Nacelles look very thin.  I'm wondering about how this would work out as a catapult glider?  What is the incidence settings on the wing and stab?

Tom

Title: Re: Tether Flying for S&T models
Post by simpleflyer on Oct 2nd, 2012 at 8:57pm
The two doublers on each side of the front of the model are 1/16 sheet.  The remainder of the model is 1/32 sheet.  The tail parts and outer wing sections are sanded even thinner. 

We are trying to minimize weight at the back of the model and build more weight into the front, so we won't need to add extra weight to the model to bring CG to the forward part of the wing, which is usually the best location for swing control flying. 

The incidence is about 3 degrees, more or less, usually built into the tail.

This model has a twelve inch wingspan, IMHO 1/32 sheet structure might be a bit flimsy for catapult launch of this model, especially if strong elastic is used for launching. 

A while back we built some backyard 'zip' gliders.  They were mostly in the 6 to 8 inch wingspan and mostly of  1/32 sheet.  They flew OK. but we were using small office type rubber bands looped together for power.

Here are a couple pictures of these small gliders, nearly all of them less than 8 inches wingspan.

The profile Mustang had a bit of an incident over the past weekend.  Sunday was a beautiful clear and warm and seemingly calm day.

So Norma, her sister, and I decided to go to the neighborhood schoolyard to fly.  We grabbed a couple of poles and a handful of planes and off we went.

They have a nice open field there.  So we parked the car next to some trees so the girls could stay in the shade and we began flying.  Looks like the warm sun was causing risers to form in the open field as every once in a while a quick breeze would come over the trees into our flying area.

During one of the breezes the Mustang made a hard nose first landing, breaking the fuselage in two.  Apparently, at one time I had partially start cutting a balsa sheet and changed my mind and put it away.  When using the sheet for the Mustang I overlooked the partial cut.  The repair will be easy enough and the Mustang will be flying soon.

Although the mornings are chilly, later in the day it warms up and the sky remains clear with light breezes.  Great days for flying.  Today we flew a couple of the older 'swingers'.

First a much modified CloudBuster with a FlyBoy wing.  Then our first modified CloudBuster with a new CB wing.

Both flew well until running into an occasional gust, then the model departs from a stable flight pattern.  That's when the tether line proves its value,  Usually. the flight can be salvaged and model damage is minimized.

Thank you, Tom and Eric, for your comments.  Yes, we've been blessed with some nice winter days here in Texas, but the rain is declining, so we may be in store for another hot dry summer. 

The nice weather is been keeping us busy with household and other tasks and swing models have been laid aside for a while.  Hope to back to building and flying soon.

Eric, the clamps are cross action tweezer type clamps about 6 inches long.  We bought them at Radio Shack a few years ago.  I have not been to Radio Shack for awhile, so I don't know if they are still available.

After showing the Jim Walker FireBaby model on Tom's old model thread, we took another look at the parts and decided that the FireBaby could be made to fly as a swing control model.

We wiped and lightly sanded off some of the old fuel residue.  Some of the wood was cracked so we repaired it with glue.  For nose weight a non-running Cox 020 TD was attached.  The TD had just enough weight to bring the CG in the correct range for swing control flying.

As a swinger it presents a sensation very similar to
what we experienced when we flew half-A models as a youngster.  Some differences are that it is easier, quieter, and can fly in the back yard as opposed to traditional CL.  This experience encourages me to try building more of these old half-A CL models for swing control flight.

Thank you, Tom, for your kind comments

We've found another sweet flying swinger converted from a Stanzel Flash 500.  Conversion was easy.  A simple removal of the prop and drive wire and wheels.  Then a bit of weight added to the nose to replace the removed parts.

We had the good fortune of coming upon a couple of these at the local Wal-Mart several years ago.  A pity that the Stanzels and their fine products are now history.

But, we took a pic of the parts to be used in making a 'scratch built' version of the Flash 500.

SimpleFlyer,

Can't tell you how much seeing the flying shots transform that model.  I've had a few of those in the past and when the grandson's kinked the wire so they wouldn't fly any more, wish I'd thought of swing flying.  You'd have thought that would have been a natural progression. 

Really great to see them flying.  I noticed you reinstalled the landing gear.  Thanks again for the great flying shots.  Very inspiring [smiley=thumbsup.gif]

Yes, it would have been a good way to recycle your grandson's damaged Flash 500s.  As a youngster we used swing flying on a couple of instances, but it is only now that we are recognizing so many new applications for flying by swing control.

The landing gear was reinstalled in an attempt to try some "touch and go" and full stop landings.  But our landing area is less than ideal, and we tend to come in too fast so the gear shifts and starts to wrinkle the thin fuselage wall, so we're going to remove the gear.

Those were the days! All I had to worry about was how quick I could jump under my desk, while in school, when there was a siren wale! I had a whip plane, I think Jim Walker may have had available, over fifty years ago. What fun it was, whipping it around on a 15' fishing line attached to the nose of the balsa fighter plane & a 10' bamboo fishing pole. I remember my flying friend & I was falling down, dizzy & giggling & laughing. Lots of fun, even if the plane didn't fly that great. Thank for the Memories.  ;D

Thanks, peekaboo, for your comments and sharing your memories.  We did a bit of swing control flying as a youngster, before getting into controline model building and flying.  Now that we are in our second childhood ;), we have learned that swing control is more do-able and rewarding activity.

Recently, we were browsing the Guillows web site and came upon their commercial foam gliders at.

http://guillowgliders.com/foamgliders.htm

They remind me of the original 'ZIP' gliders except for the fact that they are now made of foam and are sold in bulk as advertisement 'freebies'.

A couple of the gliders appeared to be suited for quickie inexpensive 'ZIP" swingers. Namely, the Logo Jet and the Logo Mono Plane.

Post by simpleflyer on Aug 26th, 2013 at 11:20pm
We found that by clicking on the models name or image would lead to a page with further description of the model with a link to a PDF pattern of the model. So we captured a bunch of the patterns and added them to our ZIP-model plan collection. In the line of foam gliders are the Space Shuttle and 7 jet airliners and a few odd types for a total of 12 models.

We printed the Logo Jet and Logo Mono Plane patterns to a sheet of paper and scanned them. Then worked them over in MS Paint and came up with this pair of images that could be printed to a letter sized sheet of cardstock.  We added doublers to both models and made a few mods to the Logo Mono Plane.  Changed the forward fuselage and modified the tail for sheet wood construction.

The pattern image was printed to cardstock and the parts for the models were cut out. Some scrap foam from some fast food or left-overs containers was scrounged up. Here are the patterns and materials for the 2 models.

The Logo Jet builds up quickly. Outboard trailing edges are scored with a metal ruler and bent up for elevons. One of the doublers is glued in place. A few flattened lead BBs are taped in place for preliminary balance. A temporary attachment loop is taped to the wing tip and the Logo Jet is ready for flight test. A couple hand tosses show that it flies sorta level with a bit of turn.

Post by simpleflyer on Aug 29th, 2013 at 8:38pm
A while back we started building a series of 'ZIP' models of the different types of airplanes that we had flown in during the first 25 years of our life.  This will not be too difficult of a task as there were only about fifteen flights in ten different types - Navion(1954), Stinson L-5(1954), C-47(1955)(1963), C-119(1957)(1958), C-46(1957), Lockheed Electra(1961), C-118/ DC-6(1962), Grumman C-1(1963), C-121(1963), Boeing 707(1963)  In those years, flights in an airplane were an infrequent event in our life due to their cost.  All but one of the flights were courtesy of the Civil Air Patrol and the US Air Force.

We began building the models in the order that the flights had occurred.  So far we've completed the first six:  Navion, L-5, C-47, C-119, C-46. Electra

Pictured below is the C-118 that we were flying in on a flight Between Travis AFB, CA and Itazuke AB, Japan.  This was on the leg between CA and Hawaii. 

This flight back in l962 consisted of 3 segments to get to Japan, with one more segment to get to Itazuke.  A few years ago Norma and I flew back to her home in the Philippines on a 2 leg trip between CA and Manila.  One leg was San Diego to Taipei, nonstop.  An amazing and long flight.

.....back to her home in the Philippines on a 2 leg trip between CA and Manila.


This is excerpted from the message above with the pix taken from the C-118 over the Pacific.  Manila is located on Luzon the largest of the Philippine Island group. . Across Laguna Bay south of Manila is Los Banos. Norma's home town. Norma was born there in 1941. In 1945 the US Army's 11th Airborne assisted by Philippine guerrillas conducted a raid on an internment camp held by the Japanese and successfully extracted the POWs with no loss to the prisoners or main attack force.

http://www.rememberlosbanos1945.com/

As reprisal after the raid, the Japanese massacred some 1500 residents of Los Banos. Luckily, Norma's Mom and siblings escaped into the nearby mountains and survived. Unluckily, her dad who was a Filipino guerrilla did not survive the war. The 11th Airborne to this day provides generous financial support to the Los Banos Rural High School. On one of Norma's return visits to home, we were able to visit the Los Banos RHS. Her university graduating class had build some covered walkways for the school.  Today, Los Banos is a fast growing and thriving town with litlte residual effects of those dark brutal days of a time past, but should not be forgotten...

Our other foam "ZIP" model is the Logo Mono-Plane.  the pattern for the parts is in the image back in post #176.  The building procedure is pretty basic so I will just post a series of them prior to the test flight.

The foam Logo Mono-plane is ready for flight. Next to it are patterns for cutting balsa for the C-118 ZIP 'swinger'.  Test flights of the Mono-plane went well. On one of its flights it picked up distant wingman off of the right wing.

Great Stuff on the foam flyers...what kind of glue do you us with the foam?  How long does it take to set up?

Tom

Title: Re: Tether Flying for S&T models
Post by simpleflyer on Sep 3rd, 2013 at 5:05pm
Thank you, Tom.  I. too, was surprised how they turned out.  Past experience with tailless models has been mixed, some good, some not so good.  Plank type wings have been suspect to me.  But this one turned out quite well.  I think the secret is the tapered elevons. 

We used Elmer's wood glue on the foam.  We were wondering how the lack of porosity of the foam and glue would work out.  But the 'stickiness' of Elmers seems to hold on to the foam OK.  We thinned the Elmers a bit with water, spread a thin coat all over between the two parts being joined and let them set up a few  minutes and clamped them together.  It seems to hold OK.  Set up time of maybe 10-20 minutes is sufficient to handle the parts gently.  For flying, let it set a couple of hours or more.  Overnight, the joint is pretty much permanent, especially if it soaks into the material being joined.

An observation re the thick foam on the Logo Monoplane.  The foam was about 1/8 inch thick.  The thick flying surfaces without rounded edges seemed to fly stably and slow.  Seems the airflow around the wings is more 'fuzzy' making for more drag and slower flight envelope.

Work on the C-118 is slowly making progress.  Some 1/32 sheet balsa has been transformed into a 'ZIP' kit of the C-118.  The fuse doublers are 3/32 sheet.

Fall arrived with some much needed rain this past weekend.  Monday was cloudy and a bit cooler.  Just right for some late afternoon flights. The first picture shows all that is needed for an impromptu backyard flight. 

The model is the wing and tail from a Guillows FlyBoy attached to a simple stick fuselage.  One of our favorite flyers. 

The only other item needed is our trusty collapsible Shakespeare pan fish pole with a twelve foot line.  It doesn't get much simpler than this.

The model in back of the FlyBoy is its reflection in the sliding door.

The modified FlyBoy enjoyed the nice afternoon very well.

Great stuff with the C-118, was that the military version of the DC-6 or the DC-7?  or am I in the ballpark at all?

I am surprised the main wing is 1/32 instead of 1/16 balsa.  Will there be a foil curved into the wing or will it be a flat wing?

This is looking great.  Always loved the radial engine planes.

Tom

Title: Re: Tether Flying for S&T models
Post by simpleflyer on Oct 2nd, 2013 at 11:54pm
Thank you for your kind comment, Tom.  You are correc, the C-118 is the military version of the DC-6.  This model's wing span is only ten inches, so the 1/32 sheet balsa is sufficient.  The wing chord is less than 2 inches, so no curved airfoil will be used.  I once read an article on model aerodynamics discussing airfoils and it said that on wing chords of less than 2 inches, airfoil curvature had little effect.  At this size flat wings worked almost as well as curved.  My experience with small models seems to bear this out.

Made some on the C-118.  The horizontal tail has been attached to the fuselage, wing dihedral formed, and wing was glued to the fuselage.

I found in my CLG's (Catapult Launched Gliders) that the flat wing worked quite well and on some out performed the wings that were sanded into an airfoil.  Do you remember where you read that article from?

Sounds like something I like to read. 

Love this C-118.  As good as she looks, I'm sure she will be a great flyer.  Keep up the great work.

Lately, we have been having quite a few nice cool days with lots of blue sky . Norma had to bring a car load of stuff to her friends in a small neighboring town. I agreed to accompany her and help her make the delivery if we could do some sightseeing on the return trip home. I wanted to visit Lane Airpark which is the local airport about two miles from where we live. So on the return trip, we made a stop there. The airport owner and main activity on the airport is Lane Aviation. http://laneav.com/ .They are very friendly folk and allow me to wander about the airport as long as I keep out of the way of the airplanes and the workers.  If you go to the link a couple sentences back and click on it and then click on the link 'about Lane', there is a nice aerial view of the airport. 

The first picture shows the main office and hangar for visiting aircraft.

Next is the parking ramp with the office/hangar to the left and the fueling facility to the right and a single 5,000 foot runway is behind us out of the picture.

Next pic shows two of their maintenance and storage hangars. The white rounded roofed one is probably their original hangar.

In the white hangar we found an Air Tractor 401B.

Next to the white hangar are two additional newer hangars.

In the first hangar were three turbine powered Air Tractors.

In the last hangar was solitary Air Tractor undergoing an annual inspection.

If the look of the Air Tractors seems familiar, think "Dusty" from the Walt Disney movie "Planes".

Glad that you liked the tour.  Merry Christmas to you and the rest of Stick and Tissue.

After the Lane tour, I read about lane and Leland Snow and the Air Tractor.  Got me to thinking of making another model for the 'famous aviator and plane' cookup.  This one for Leland Snow and the Air Tractor.  He was quite a remarkable person and the story of the Air Tractor is interesting.

This past weekend, Norma and I attempted another tour, but it was a bit incomplete but eventful, just the same.

After Church, Norma wanted to go out and eat lunch  at the Oakridge Smokehouse in Schulenberg TX.  It sounded like a good idea as we could go to see the Stanzel Brothers museum after lunch.

Lunch was great, but the museum is closed on Sunday.  But we were able to make a few flights of our Flash 500 with the  museum as the background. 

We have some stuff on this thread about the Flash 500 at:

As this year ends, we are enjoying some nice weather at times. Today was another one of those great days for flying. So we took out a few of our ZIP swingers for some flying. First the little P-84 is framed by the neighbor's Sycamore that is still dropping leaves, at least they are falling into his yard instead of ours on these relatively calm days.

Next is the sheet wood A-26 Tradesman, a remarkable flyer for a 12 inch wingspan.

Another pic of the Tradesman showing some of our cloud cover at midday, expanded vapor trails from overhead aircraft.

Finally, the little Foam Wing.

Cheap flyer. Plans downloadable from Guillows for free. Building material is recycled food take-out trays from our favorite eating place away from home ;)

Pic taken at dusk shows a dramatic change in the weather, forcast for tomorrow overcast and cold, so this years flying will be coming to an end.


Wishes to all for a good and healthful new year.

A couple of days ago, the weather cleared and we decided to do a bit of flying in spite of the breezy conditions. We've been gathering information about 'nickle and dimers' so we decided to pick a couple from our fleet of 'swingers' and attempt to fly them. A while back we built a Ryan ST from the Comet W series. The structure was modified to imitate the style of Herb Weiss'es 'Minute Models'. The fuselage sides and tail surfaces are made of 1/32 sheet and the wing and fuse top and bottom are stick and tissue.

Thanks for your comment, Tom.  A couple of days later we were doing some touch and goes on the patio at the back door.  The little Ryan encountered a challenge that was more difficult than a brisk wind, a brick on the patio which took off the outboard wing tip as the Ryan taxied by.  A bit of glue and a bit of balsa and tissue and the Ryan will be flyable again.

One of our outdoor tasks in the back yard was to remove a couple of dead branches from a fence line that we share with our neighbor.  The removal of them will reduce one of the sources of conflict for our swing control models.  The planes have made contact with the branches in the past.

Thanks, Bob and Tom, for your interest and comments re the 'swingers'.  Construction of these has slowed a lot due to domestic chores.  The first quarter of the year is always filled with these tasks and each year we seem to get slower in accomplishing them.

We did have a couple of good flight experiences with our profile  F-100 model.  Many years ago at a faraway place we spent several months working on the F-100 (aka Hun) at Itazuke Air Base and it became a favorite of ours.

A few years ago we built the the profile model pictured below.  After which, we entered into the practice of locating Huns and trying to get an opportunity to fly the model Hun in the presence of the real item.  The 2nd picture below shows our first attempt at the Louisiana Maneuvers Museum at Camp Beauregard in Pineville Louisiana in 2010.  The F-100  is a bit difficult to spot just under the canopy of the display craft.

Recently, we had two more such flight opportunities.  Two weekends ago, Norma and I made a visit to Galveston, TX.  They have a F-100 on outside display at the Lone Star Flight Museum there.  We had a nice and interesting visit of the museum and were able to snap the shots below after the visit.  It was a bit chilly and a tad windy, but a flight was accomplished.

The second opportunity was at La Grange TX this past weekend and we will post pix next time.

Thank you, Tom, for your kind comments on the flight pictures at Galveston.

Here are the pictures of the F-100 model's flight at Fayette County airport in La Grange, TX on this past Sunday, March 30th.  The weather was much better, although still a bit breezy.  Norma was using her digital camera which is better than my little Kodak that I normally use.  She is more familiar with her camera and the picture results are better.  We were  making an afternoon tour of Bluebonnet country and I was able to con her into making a swing by the Fayette County airport and capture the pix.

The F-100 on display at the Fayette Regional Airport was a project by the local citizens to establish a memorial to remember the brave and capable USAF pilots that serve and protect our nation.  The Thunderbird markings are in honor Rusty Keen, a local young man who joined the USAF and ultimately was selected to fly with the T-birds around 2005-2006.  He flew the #2 position flying a F-16.  The airport terminal has pictures and data about Major Keen including one of his T-bird team uniforms.

A mini-bio of Major Keen is at:

Thanks, Bob, for your interest in the F-100 model.  We do not a proper plan for this model.  This one of a series of 'quickie' models that we build in a modified format of the old Guillows ZIP profile gliders.

Usually, we take a 3-view drawing of the model that we intend to model and take the major shapes from the drawing and turn them into a template sheet and start building from scratch and see where it goes from there.

For the F-100 we borrowed the shapes from a 3-view of the F-100 drawn by Walter M. Jefferies and came up with the pattern shown below.

The only dimension that needs attention is that the upslope of the rear fuselage is 3 degrees.  The wing  and horizontal tail mounting locations have been moved to the underside of the fuselage at the blue lines.  The wing and tail surfaces are 1/32 sheet.  The fuselage is 1/16 sheet with a 1/8 sheet doubler on each side at the nose.  The red lines indicate the shape of the nose doubler.

The story of the build can be found at the Small Flying Arts Forum at:

Your build brought back many happy memories and l did not know that we had a TEXAS boy in the Thunderbirds at any time, this makes me happy. l reviewed the SFA link and saw your tether control rod and understand a little more how you accomplish your flying. What length and what type of line are you using?

Thanks for the descriptions and plan know how it has me seriously looking at trying one now.

Thank you, Bob and Tom, for your comments and continued interest in the 'swingers'.  I do hope that you have a chance to try them out.

Here is a plan for a quickie swinger that can make the process of trying swing control pretty simple and inexpensive.

Only a few materials are needed.

Using fast drying glue the model builds up quickly.  We built up a couple this afternoon and were flying one of them before sunset.

Bob, one of the sketches on the plan illustrates an easy quick rule of thumb for determining line length for swing control flight.  We often use a longer pole than the one suggested on the plan.  Our favorite swing pole that we currently use is 12 foot telescoping pole.  With this pole, on windy days we use a line length equal to pole length.  In calm conditions we can use lines up to one and a half pole lengths long.  Perhaps a bit longer if we fly in an area larger than our back yard.

Its named 'Quick Grip' manufactured by Beacon Adhesives.  We bought it at the local Wal-Mart a couple of years ago.  We have not checked lately it they still carry it.  It is clear and drys quickly much like Duco.  It seems a bit thicker, but that may be because the glue is slowly drying in the tube due to passage of time.

Back in January we participated in the Comet 'dimer' cook-up and built a much modified Phantom Flash.  The modified PF turned out to such a nice flyer that we have decided to do more work with this design. 

Here is a picture of our first three versions in the family and we are going to call them the 'Simple Swingers'. 

On the left is the original modified PF, in the middle is streamlined fuselage version with a modified Guillows GoldWing glider wing and tail, on the right is another modified fuselage with a mid fuselage mounted wing.  All versions have removable wings and horizontal tails.

The T-28 is a great plane.  If I were doing it I'd go with the black scheme used by the squadron at Beal AFB, used to be home of the Blackbird SR-71's and still the home of the U2R's and U2CT's.  They use the T-28 for proficiency training. 

I ask an SR-71 pilot what it was like to fly the SR-71 and he said it was like flying the T-28 under the hood on instruments all the time!!!

Tom, we don't have much to report on Model-Mania.  It is a plastic model contest put on by the Houston IPMS.  They have a large vendor area for plastic model vendors to sell their wares.  Over the years we accumulated a large amount of plastic models with the dream of building them in our retirement years.  Now that retirement is here, our model interests have returned to the balsa models that gave us so much happiness as a youngster.  And now we have a surplus of plastic that we are selling off to pay for our current model expenses.  So it works out pretty well.  Each year we pack up a bunch of models and rent a table and we sell plastic for most of a day at MM.  This year, we were able to unload the batch very quickly and were able to come home early and get back to building 'swingers' [smiley=thumbsup.gif] 

Back to the T-38.  Yesterday, the wings were attached.  By late afternoon, the T-38 was ready for a test hop.  The first flights were not very promising.  The model has a severe roller coaster flight path.  Our gut feeling is that the wing leading edge sweep back is too sharp, causing the line attachment point and CG to be located to far to the rear.

The T-38 that the markings represent is the one operated by NASA pictured below.  This aircraft came to the FBO where we were working in the mid 1980s.  To the best of our recollection, the pilot was enroute to Ellington where NASA had a flight facility.  And apparently, Ellington weather wend down and he had to divert to Wm Hobby airport.  And he came into our facility and parked the plane overnight.  Next day, NASA brought an airstart unit and they fired up the engines and flew the T-38 to Ellington.

The next two pics are a T-38 that we were able to capture on short final to Tulsa International airport in the late 1960s.  Back in the good old days there was a railroad track passing thru the north approach lights and no one would hassle you if one would walk down the RR right of way and take pix of the landing aircraft ;)

Willow Grove may be the leading reason for my joining the Navy 3 years later.

http://balsamodels.com/phpBB/viewtopic.php?f=2&t=2278&start=45

We had planned to start building the B-29 during the first week of June.  However, construction was delayed by a trip to Louisiana where Norma and I visited family and friends.  During the trip we made a side trip Shreveport where the Barksdale Global Power Museum has on display the B-29 pictured below.  Also at the museum is the Combat Skyspot Memorial also pictured below.  We sat there a few moments and read the text and paid our respects and meditated on the brave airmen who gave their lives in an attempt to save Lima Site 85.  Air Force Chief Master Sgt. Richard Etchberger was posthumously awarded the Medal of Honor for his bravery in this action.  The story of Lima Site 85 can be found at:

Below are most of the parts of the B-29 model minus the landing gear and turrets.  When built per the plan the fuselage is left uncovered.  This area is covered with a panel of paper cut from the plan.  This leaves the model with a flat bottom.  When we built these Guillow kits as a youngster, we built them per the plan.  At the time we felt that this feature of the kit could be improved upon.  Now-a-days when we build the Guillows shelf models we add some balsa to the under side so that they can be built a bit more to scale, as seen in the F-84 and P-40 shown below.

This series of pictures show the fuselage construction.  The sides and main formers are glued together. 

More material is added to inside of the lower fuselage.

A balsa panel is added to the underside of the forward fuselage and a rear under panel is constructed.

The rear under panel is glued in place.

Then the upper fuselage panel is glued in place, leaving us with a fully enclosed fuselage box that can be formed into the cylindrical shape of the B-29

Nacelle construction is also altered from the kit plan, At the top are the three die cut pieces provided in the kit for a nacelle, below is the modified structure-the nacelle top has been lengthened and a piece has been added between the top and bottom. This makes for simpler construction and adds more depth to the nacelle to bring it more into scale. As seen in the B-29 picture posted earlier, the actual nacelles have more of an oval cross section than a circle.

Another mod was the gluing of a couple basswood pegs into the bottom of the vertical tail. This allows for a removable tail and more strength in that area.

Flight pictures of the B-29.  Flies OK for a little model of barely 10 inches wingspan, but is pretty sensitive to gusty conditions and diverts into some unusual flight attitudes.

Thank you for your comments, Tom.  The sensitivity of these small models to wind and gusts is why I fly them on a short swing line, swinging them in a circle with the pole near vertical.  When the unstable air puts them out of control, there is little danger of them striking the ground.

Tom, I'm not aware of any B-29 that had such a system installed.  However, a B-17 was so equipped.  The B-17 pictured below had the Fulton retrieval system installed by Lockheed in the early 1960s. 

Dr Joe Leeker has a well documented article about this aircraft at:  http://www.utdallas.edu/library/specialcollections/hac/cataam/Leeker/aircraft/b17.pdf

An interesting read.  For more information, one may google 'operation cold feet.  Wikipedia and the CIA website also have interesting articles posted.

This B-17 survives at the Evergreen Museum in Oregon. 

One more bit of trivia before ending this post.  This B-17 with the Fulton setup had a 'bit part' at the end of the James Bond movie 'Thunderball'.

The B-17 is one of my favorite airplanes.  My favorite of all the B-17s is the one described in the prior post. 

In 1980 we had the opportunity of seeing N207EV in person.  We working a Esler Field in central Louisiana at the time.  N207EV was working for Evergreen when they were contracted by the US Forest Service during an especially dry year to fight forest fires. 

We were able to capture the pix below.

A few years ago we built a ZIP model of N207EV, pictured below..  In the future we plan to build N207EV as a 'swinger'.

That is what I was trying to illustrate with the video.  So a video shot was attempted that would would show some of the variety that is possible with swing control. 

It seems that when most people see or hear about SC, the first impression that comes up is something akin to swinging a rock on a piece of string.  Over the years, I've discovered that there is bit more to it than that.  Looking forward to improving my video skills to be able to illustrate SC flying better.

This version of the SS will be called the SimpleSwinger 16 because of the 16 inch wingspan.  It was completed and flown last month, but we kinda got busy with 'other stuff' so the rest of the story of the SS 16 will be posted now.

The model will be a mid-wing model with the wing embedded in the profile fuselage.  To accomplish this a cross-grain piece of 1/16 balsa ties the two wings together forming the dihedral.

Next we add the ribs at the dihedral joint.  They are made from balsa about 3/16 inch thick and are spaced about 1/16 apart.  The rib thickness provides area for attaching tissue when it comes time to cover.  The remaining wing ribs are two strips of 1/32 balsa with a spacer at about 40% of the wing chord from the leading edge.

The fuselage parts.  The forward fuse is basically 3 layers.  If additional nose weight is needed 2 more layers will be added at the nose tip.  The middle layer is made in two pieces.  The front of the tail piece is pointed at the end of the slot so that it fits snugly with the nose piece.  The two side pieces a slotted so they can fit over the wing.  When gluing the 3 nose pieces together care must be taken so that the bottom of the slots in the side pieces match up with the slot in the mid piece of the fuselage.  I like to call it the 'minnow' fuselage, as it reminds me of the minnows that I would see when I would go fishing as a child.

Then push the pointy part of the tail piece until it is snug in the  nose piece.  The assembly of these pieces now capture the wing into the middle of the fuselage.  By making the slot in the tail piece an inch longer than the slots in the nose piece, this leaves room for about one inch of adjustment for final trimming for flying.

It was really too windy to fly so the flight was not very good.  Looks like we hit the swing pole on one of the flights and sustained some damage.  Some quick drying glue took care of the damage, so the Stinson will soon be flying again.

After adding the nose weight, we were anxious to see how the model would fly.  It was windy to try a test flight with a swing pole.  So we took a bit of blue tape and attached a bit or thread to the wing tip and took it outdoors to make a few hand swings between wind gusts.  First swings indicated that the SS-24 wanted to fly.

After after glue dries, the tail parts are removed from the building board and checked for fit, which is OK.  Building the tail surfaces over the tissue allows the construction and covering to be accomplished in one step.  The tail surfaces will remain covered on one side only.  This was done on the SS-24(modified FireFly) and it flew quite well.  All that is left to do on the tail surfaces is to trim the excess tissue, shape the tips, and apply a couple of coats of thinned white glue to fill the tissue pores.

Next is to build the forward fuselage on the SS-30.

Looking great Al,

I just can't resist saying colored markers are needed on the P-40... :D ;D she just needs some makeup! [smiley=thumbsup.gif]

Hope the weather permits so we can see pics of them in the air soon!

Tom, we'll try to add some decorations to the P-40.  At least ink in the control surfaces and maybe add some insignia.

More time for building is becoming available, so we were able to cut out the forward fuselage parts for the SS-30.

The forward fuselage is glued up, need to punch a hole in the nose for a nose-weight cavity and then glue the covers in place when the amount of weight is determined.

Wing center section and dihedral is formed.  At 30 inches this is the longest wing that I have built in over 40 years.  Covering this wing using thinned white glue and tissue will be a bit of a challenge.

Thank you for your comment ,Tom.  There is a bit of reluctance  to cover up the wing structure, but it is replaced by the the anticipation to see how well the model will fly.  The increased size and refinements made to the Simple -Swinger design are an incentive to get this model into the air as soon as I can.

Test fitting the wing to the nose section shows the CG to be just to the rear of the wing trailing edge at this point.  We're thinking of shortening the tail stick about and inch and a half , which would be easy at this point.  Tissue and painting will bring the CG even closer to the desired location.  The shortened tail stick would reduce the amount of extra nose weight that would be needed later.

At first I thought the wing slipped on to the fuselage from the bottom of the fuselage....but in reexamining the pictures I see it passing thru the fuselage.  Which eliminates the ideas I had of sliding the wing back.  I await you pictures of the solution!

I know you'll have her flying soon!  Can't wait! [smiley=thumbsup.gif]

I like the spar construction, it looks like it is a warp free techniuqe and I always have that trouble with my wings. So I will keep this in mind for my next build.

I really like the design also.

Thank you, Tom and Bob, for your comments.

Tom, the slot for the wing extends about half an inch on each side of the center chord allowing some movement fore and aft for final trimming.  Also we have shortened the tail stick by about an inch and a half.  Weather here is wet and cold up until Sunday.  We're aiming for early next week for a test flight.  Yesterday, we covered the top surface of the wing; today we hope to cover the bottom.

Bob, The wing is made from ribs and spars from a Comet kit of the Comet Phantom Fury.  The under camber was trimmed off to make a flat bottom wing and an extra spar was added and the leading and trailing edges were beefed up.  The tail surfaces pretty much followed the kit plan, but made from 1/4 wide strips of 1/32 balsa covered only one side.  Diagonal strips were incorporated in the tail parts to maintain  rigidity.  So far the structure seems to remain straight.

After our experience with the Phantom Fury wing, we're thinking of experimenting with a simple wing.  Jetco Model co. used a nice simple wing in some of their rubber powered and glider designs that they developed for beginner modelers.  We have the good fortune of having several of these kits.

We'll start with the wing of the Jetco Hawk, a simple rubber powered model of about 24 inches W.S.  The picture shows the parts of the wing.  There were only two spar with 9 ribs per side.  For the 'simple swinger' we've increased the rib spacing so we have a few ribs left over.  These will be used in the next swinger.

The wing center section is formed.  The wing span of this model will be about 24 inches and will be designated the SS-24JH.  The spacing of the center ribs will be changed from 1/16  to 3/16 inch.  The two part fuselage is being simplified and will require this change in spacing.

The extra ribs from the Hawk will be used for the wing of the SS-36JTC.  This wing will be about 36 inches in span and very similar both in span and construction to Jetco's Thermic C marketed in the 60-60s.  We started building one of these as teenager but did not complete it,- became too busy with flying U-control and trying to graduate from HS.

In the 50-60s we built two Jetco Troopers.  This was the second one.  The damage is due to storage/handling.  We tried tow-line launch back then, with mixed results.  Folded the wing on one launch.  The craft did have a nice flat glide, when hand tossed.  Don't remember if we ever tried 'hi-start' with a rubber and string catapult.

Thanks, Bob, for your comment.  Our first successful rubber powered SnT model that flew was a Jetco ROG.  We really liked the simple easy to build structure of the Jetco smaller models.  Fortunately, our modest collection of these has survived to now and we are enjoying the opportunity build them at last.  Looking at the Trooper, I have another of these kits and I think I will add it to the 'simpleswinger' fleet.

Correct, Tom, its thinned Elmers white.  Actually I'm a Dr Pepper-upper, The Pepsies are left overs from a recent birthday party that Norma had at our home.

Re, the wing cover.  When starting the wing cover, the paper is tacked with thinned Elmer's wood glue to the wing panel at a few ribs in the middle.  When the glue drys enough to hold the paper in place, we start applying the thinned white to the wood adjacent to where the wood glue was initially applied, and go out to the edges in all directions trying to keep the tissue as snug as possible.

First pic shows starting the process, the second shows the completed wing for the SS-36JTC.

The first couple of weeks of February were sorta busy and modeling and flying were curtailed a bit.  The first week we had a birthday(the big 75) and a trip with Norma to Louisiana to visit with family there.  One high point of the trip was an enjoyable visit to the Chennault Museum in Monroe Louisiana.  We'll comment more about the museum later.  The second week had a lot of unseasonably warm weather so we were occupied with a lot of yardwork and chores.  Cold weather has now returned  and we've been able to return to our models.  Work on the Begulne has been shelved  for a while and we've returned to our favorites, the simple swingers.  Here is the covered wing of the SS-24JH.

To fit the wing to the fuselage, the forward fuselage is slid into the gap between the center ribs.  Then the pointed part of the rear fuselage is slid into the slot in the forward fuselage and snugly captures the wing into place.

Since the SS wings with the 3/16 center ribs spacing are interchangeable with the other fuselages in this segment of the SS series, we decided to try an experiment.  We took the SS-24JH wing and fitted it to the fuselage used with the SS-30/36 wings and kept the Firefly horizontal tail. 

Fitting the long fuselage to the 24 inch wing wing is effectively clipping the wing span by a third and makes it a faster flyer and punches thru the breezes quite readily.

After  the close-out sale of the 12 foot Durango pole we did not see it return to the local Wal-Mart shelves.  We've Googled the pole and it seems that Shakespeare has discontinued it.  It seems that they have replaced it with five section 16 foot pole.  It seems that the longer pole would perhaps be a better pole for swing flying but it costs more.

A few posts earlier we mentioned our experiment with the combination of the 36 Zaic wing with a fuselage for a 24 inch model. This combination is pictured below.  This combination has a lighter flying weight.  However, the lighter weight requires a longer nose moment so the nose had to slid forward about an inch and a half and the wing had to be moved to the rear most position in its mounting slot.

A good time to stay indoors and build models.  This past week we completed the SS-25CB.  We took the laser cut wing ribs from a Guillows Cloud Buster and modified it.  Using the CB wing  plan for a guide we redrew it and extended the wing span and changed the angle of the wing spars.

We have a couple of Comet Meteor kits from which we borrowed the diecut ribsheets, strip wood, and tissue for our next SimpleSwingers.  The wing of the Meteor is the same as the wing from the Comet CloudBuster which later becomes the Guillows Fly Boy.

The Cloud Buster/Fly Boy as built per the plan is 21 1/2 inches.  For this version of the SimpleSwinger the wing will be expanded to 40 inches.  The modification begins with changing the outer panels to a double taper format and extending it to 13 1/2 inches.

A bit of trivia about the Meteors and Fly Boy/Cloud Buster.  The first picture shows our two Meteors.  We bought them in Houston in 1986 for $3.28 each.

The next pic is a scan from an early Comet catalog showing the Cloud Buster priced at $1.50.

This past December laser cut rib sheets for the Cloud Buster and Fly Boy cost us $ 2.50 each.

Current MSRP for the Fly Boy is $ 21.79.  Isn't progress wonderful :o

Thank you, Tom for your comment and interest in the SS-40.  Progress on this version has slowed a bit as I am being distracted with some other projects such as IRS filing, yard work, and a Hawk 75 project that I want to begin soon.

Got one panel glued up and drew the center panel and began gluing on it.  The wing will consist of three 14 inch panel joined together.

Well, we're back after some spring distractions.  Back to work on the SS-40.  We were able to get the center section built and the remaining panel should be finished soon.  Yes, Tom, at over 40 inches it will be the largest wing that we have built in recent years.

But it wasn't always thus.  In my late teens in the late 50's, we made a largely scratch-built Ukie-goat(trainer) of about 44 inches wingspan powered by a Fox 35.  Was a hoot to fly.

Thanks, Tom, for initiating the U-Control thread.  We'll to drop by there and share some of our mis-adventures at the flying circle so many years ago.

The three panels are constructed.  Now the challenge is to connect them together.  We fitted the center panel to our longest SS fuselage and it fit OK.  The panels were placed together to get an idea of what the craft will look like. 

Tom, I'll try to post some stuff to the CL thread, soon.

Bob, the CL model is the picture is CL model that we built from a model that we tried to build for RC.  Reading about RC models in the model magazines at that time gave me the idea to try one.  We started the model in the image attached.  It was not full size, but from the data presented we were to build the wing and much of the fuselage.  Then we started getting the bits of the RC system together.  Back in the day not much RC gear was available and not affordable to our ambition so the project was abandoned to simpler and affordable CL.  We built a simple sheet balsa profile fuselage and sheet tail surfaces.  Added a second bellcrank and rigged up a push rod to a crude clapper fitted to the venturi of the Fox 35 we were using.  Ran a 3rd line from the second bellcrank to our E-ZJust CL handle and with our free hand we would pull the 3rd line and able to slow the model enough to make touch and go landings. 

We'll try to edit the image below and sketch in what the model looked like,

Last night, we were organizing and editing some digital pix for some future posts to the web.  Also we were reading some of the forums and doing some Bing & Google mapping.

Kinda late into the evening we were noticing some weather activity - falling rain and a lot of thunder/lightning.  So we checked Weather Underground and saw some interesting radar maps showing a line of orange and green blobs over SugarLand near where we live. 

The blobs continued to grow instead of diminishing.  This was confirmed by the increase of rainfall and rate of thunder/lightning activity.  Now we began to look outside to see what was going on.  Thru the windows we could see rising water in the street in front as well as in the backyard.

About 1 AM we captured the blurry pic below.  The water at this point is curb to curb and above the middle of the street.  About 2 AM the radar blobs began to diminish and move eastward, so we decided to go to  bed.

We arose early and things were quite outside.  So we went outside.  Rain had stopped and water in the streets had gone down.  In some low areas of the street the water covered the street, but was quickly draining off.  The back yard was also draining well, but the lowest back part is still under water as we write this.

Before noon, blue sky returned and we were able to find a spot dry enough to fly from and give a trio of the simple-swingers some air-time.  First a few pix of the backyard and the SS-40.

Hmm, looks like life and its distractions has kinda overshadowed our model flying and building for a while.

As mentioned a few posts back, we had some high water in the backyard which caused some inconvenience there.  One was the rearrangement of our plank walkway to the back gate.  First pic shows next day after the rain and the next pic shows the repair.

The other issue was the high water rise that reached into  the tool shed. 

The first pic shows the water the day after the  rain.  During the night the water rose to about a half inch over part of the shed floor but caused no damage. 

The next pic shows our attempt to dig a ditch along the fence to try to drain the water out of the yard.  At the red A and B we dug beneath the fence to divert the water to a ditch outside of the fence.  With the next heavy rain, we'll see if it works ;)

However, back in May, we had some interesting flying sessions while visiting my sister in Louisiana.  Norma and I both have sisters in the central Louisiana area.  While Norma visits with her sister in Alexandria, go to our home town of Kolin LA and visit with my sister.

Often, on these visits, Sis and I go on short roadtrips to remember old times.  This time I brought a couple of 'SimpleSwingers' along.

First we stopped by Esler Field.  Esler was built during WW2.  It was one 3 USAAF fields built in central LA.  They were used for training B-17 crews prior to going overseas.  Bert Stiles author of  'Serenade to the Big Bird' did his B-17 training at Alexandria.

After WW2 Esler was turned over to the LA National Guard.  In the 1960s to the early 2000s it was the civil airport for central LA.  After England AFB at Alexandria was closed it became England Air Park and the civil airport for Alexandria.  At this point Esler was returned to the Louisiana National Guard and serves some  civil air traffic.  In the 1970s we worked several years at Esler as a mechanic, lineman, and line chief.

On this visit we made a couple of flights on an open field next to the airport, with SS-42.

In the first picture, the building between the SS-42 and myself is the main hangar at Esler.  It is the only original building remaining from WW2

In the second picture, the white roofed building is the second hangar/office building built around 1970.  It is there that I worked for 3 FBOs:  Air Charter, Ascent Air, and Crest Air.(Not at the same time,  because of economics and management issues the FBOs changed often, so we just went along for the ride and hung on. ;D)

From Esler Field, Sis and I went down the road to Camp Beauregard at Pineville, LA.  At Camp Beauregard they have the Louisiana Maneuvers Museum with a few display aircraft:  Huey, F-100, and F-15.  Having spent some time with  the F-100 in 1962 and 1963, we often try to visit with one whenever we can.

So we visited the one at Camp Beauregard and Sis took a couple of pix.

At the end of the road trip we made one more flight.  We'll post it next time and put it on the 'going in circles' thread.

Thanks, Tom, for the link to your F-100 build.  I read some of it and looked at the pictures.  It is an interesting process and produces a nice looking model.  However, it is beyond my rather simple building skills.  I think I shall stick to more traditional and simple stick and tissue construction.  The Comet F-100 plan is also interesting and I may end up building it instead of the Skyleada - decisions , decisions

Just forget the lost foam fuselage and build it per instructions.  I just had to experiment with the lost foam after seeing Tom Arnold's model on HPA.  It was a Convair 4 turboprop seaplane, forget the name right now.  Comet's F-100 is a pretty good plan also!  I look forward to seeing what you choose and how you bring it together.

We're still trying to figure out our approach to the F-100 project.  Some thought has been diverted to some of the predecessors of the F-100.

This summer has become a bit complicated with a few unexpected events and the weather has become hot and dry, so modeling and flying has sorta slowed.

Today, we took out a couple 'swingers' for a few test flights to resolve some trim issues.  A profile P-40 and profile LTV-450.  Additional nose weight solved the up-n-down oscillations and both models fly better.

Can't wait for the F-100.  I've always liked the two seat version.  I also like the taller tail than the prototype and early A models. The F-100 is a pretty short coupled aircraft.  I'm interested to see how yours flies!

The rest of the story of the LTV-450(aka XQM-93A).  A couple of months back we posted a picture of the LTV-450 on the mystery airplane thread.  Sky9pilot correctly identified the picture and we exchanged a few comments and I expressed my idea of building it as a 'simple swinger' and here is the result.

We had access to a simple 3-view of the L-450 and worked it over with MSPaint to get a page of the primary shapes.

These were printed to cardstock and cut up to develop a simple construction plan.

Using the simple plan and patterns we built a small 24 inch wing span profile 'simple swinger' of the XQM-93A.  The next step in this project is double-size the plans and build a 48 inch wing span version.  In this version, the plan is to make a two piece wing with a dihedral break in each wing panel.  Attached to this post is a pic of the remote controlled XQM-93A.

Thank you for your comments, Tom.  We, too, are attracted by the narrow wing of the U-2/ER-2.  We're strongly inclined to switch to the ER-2 in the next stage of the long-wing simple-swinger.  We've already printed some sheets of the ER-2 shapes to start doodling on.  The instrument pods could be used to strengthen and hide the mid panel dihedral break.

  You are not alone in this preference, a lot of Hun drivers had the same sentiment.  As I understand, the short tail birds had a pretty nasty departure from stable flight in the low speed envelope.

When I lived in Sacramento, CA I used to go to Beale AFB and photograph the U-2's and the TR-1's.  It was great to see all the configurations they used with the various pods, round nose and flat sided noses etc.  Some had interesting tail art as well, from cats to skunks!  Even the SR-71's had some interesting graphics done in chalk because they couldn't paint on the special coating of the SR's.  They even still had the white U-2CT double cockpit trainer that was fun to watch.  I look forward to your TR-1/ER-2 versions.

Thank you, Terry, for your comments.  I agree with you the P-40 does have simple and attractive lines, and it has always been a good flyer for me.  Recently we've developed a strong interest in the Hawk 75 versions of the Curtiss Hawk family.

At 48 inches the XQM-93A should remain a manageable backyard flyer.(Ooops, we posted the wrong designation earlier)  We've considered a 'simple swinger' of the U-2/ER-2, but I think we will stay with the XQM for now.

Thank you, Tom, for sharing you experiences of viewing and photographing the U-2/TR-s, in flight.  We have often hoped of seeing one of these craft in flight.  But no luck thus far.  However, NASA still operates 2 ER-2s at Palmdale, CA earning revenue for NASA.  They are flying missions this month.  They are known to make trips to NASA at Ellington, maybe we'll be lucky and get to see one fly before we 'conk out'.  We did get to see the one close up at the National Air & Space Museum at Washington.  The first U-2 flew in 1955 and its current evolution still works for a living 60 years later.  A testimony to the of the engineering skill of Kelly Johnson.

Post by Sky9pilot on Jul 17th, 2015 at 8:55pm
Al,

Kelly was an amazing designer/craftsman/project leader.  He came through usually with outstanding product, under time and under budget!  Also as you said, with something that soldiers on for years beyond what most thought would be a proper lifetime!  I really enjoyed seeing some of the two seaters when the instructors, I assume, would put the two seaters through their paces.  Nothing quite like the max takeoff going nearly out of sight and nearly vertical but not quite, with a short roll on takeoff.  You could always tell when the rookie landed and couldn't keep the wings level.  The experienced pilots quite often would taxi completely off the runway before the El Camino chase truck could get there with the pogo's to keep the wings level for taxing.  I remember one time the two guys in the truck couldn't get the heavy wing up and they got on the radio and called out another El Camino with several ground crew in the back and they took about six guys on the light wing before the heavy wing started budging.   Still took one more guy on the ground grabbing the wingtip to get the heavy wing high enough for the remaining crewmember to get the pogo in place.  I bet they ribbed that pilot for weeks.  We got inside for a Public Affairs Office tour and the U-2/TR-1 pilots said the early planes had manual pumps to balance the fuel in the wing tanks.  So the pilot not only had to fly his mission but maintain the fuel balance in the wings.  That was always a challenge especially when in the landing pattern.

No hijack at all, Tom,  I'm greatly enjoying your airplane stories and look forward for more.

While doing some research on the F-100, I came up on a 3 vu by Joseph Wherry of a cute stubby predecessor in the evolution of the Super Sabre.

As usual the 3-vu was tweaked a bit to get a pattern image.  This was printed to card stock and cut up for patterns to be used in cutting balsa

As we look on the last two images, we wonder if we shouldn't modify the vertical tail and fuselage notch as indicated by the red lines.  We'll soon find out.

Looks like the North American FJ-1 for the Navy.  Should make a great tether flyer! And a great EDF model.  I've always liked the looks of this pudgy little fighter, in Navy reserve markings with an orange stripe around the fuselage just ahead of the empennage!

But here's another one that would make a nice tether flyer from an early jet...the Chance Vought F6U Pirate.

Thank you for the comment, Tom.  I've looked at the Vought Pirate a few times an like some of its features, but for now, the Fury looks simpler and appealing 'swinger'.  With the cooperation of the templates, straight edge, sharp blade, some balsa, and a ball point pen we were able to come up with ready-to-assemble sheet balsa 'ZIP' no-cal kit.

Also, I think I have come to a final decision on the full body F-100 build.  I guess I will 'bite-the-bullet' and go with the Diels F-100 kit #16. 

A few years ago during Dave's year-end discount sale, we bought short kits of the F-100 and Comet Navion and some plans for a Christmas present to myself. 

At first, the complexity of the kit kinda intimidated and I was reluctant to build it.  But after our success building a Guillows Wright Flyer a while back,  I feel that the F-100 build is more do-able.  Just a matter of patience and putting it together one stick at time.

WoW Al,

the Wright Flyer is fantastic!!!!! You did an outstanding job on her! 

The Diels F-100 looks like a great kit.  I may have to look into that as well.  Love the looks of the plan and the print sheet.  I know you can build this one.  If you can get the Wright Flyer stick framework to look that good.  This full bodied F-100 will be  a lot easier than keeping all those stick square in the "Flyer". 

I'm really impressed with your Wright Flyer, Did I make that Clear?  WoW! [smiley=thumbsup.gif]

P.S. If the plans don't have the parts outlined there, I recommend making a copy of the print wood just in case you accidentally break a former or other part or slip while cutting out the part.  Trust me, I speak from experience here! :-[ :'( :o ;D ;)

Thank you, Tom, for your kind and generous comments re the Wright Flyer. 

The finished construction of the model is less my building ability than the quality and buildabilty of the Guillows kit.  Guillows put a lot of engineering and effort into their product.  The parts were laser cut, the wood was straight grained and suited for its specific use in the construction.  The plans were well drawn and a lot of instructions were included to clarify the construction sequence.  Cardboard precut jigs were provided to hold the wings in proper alignment for final assembly.  In short, if one has average building skill and can read and follow instructions it is relatively easy to have a good outcome in the building of this kit.

While not laser cut, the Diels F-100 is also a good kit.  The short kit doesn't provide stripwood so that is supplied by the builder.  There are four pages of assembly drawings including all kit parts, plus a separate sheet of building instructions.  My first task will be to make copies of the building plans so they can be reduced into scrap plans to fit my smaller building boards.  Needless to say, since this will be a 'swinger', there will be some mods incorporated in the F-100's construction.

Thank you for the link to the EDF conversion of the Diel's F-100.  The gentleman did a nice job of it, looks good.

The printed part sheets of the Diels F-100.  Good printing and good wood.  One !/16 sheet has a bit of curving, but it is for the formers and is very light and cuts easily and cleanly.  The bottom two sheets are very flat 1/8 sheet.

Started cutting the fuselage formers.  Noticed a couple of things about them.  The former halves are  identical.  They also have a line printed from top to bottom, as if one could use it as a cutting line.  We did and it was a great help in holding the halves while cutting out all the notches.  We cut the notches with a bit of sandpaper glued to a piece of 1/16 bass strip.

Wing span is 19 3/8 inches - 1/24 scale, Bob.

The fuselage structure is built using the half shell method as shown in the illustration below.  The model is designed for rubber powered flight, so for lightening and the rubber the interior of the formers needs to be cut out.

However, since we intend to make our F-100 a swinger we'll retain it for added strength of the fuselage structure.  The minimal extra weight should be offset by not using the prop and rubber.

Also, Diels half shell fuselage uses main stringers laminated from three 1/16 striips spliced at mid-fuselage.  Looks like a lot of complicated structure for a simple builder as myself.

To simplify the structure, we'll glue the former halves together and punch a hole in each one and slide them onto a wooden dowel for a simple positioning jig, adding the stringers and keels to the formers while attached to the dowel.

Al, I think you're going to like this model.  I like your idea to use solid formers and the shaft through each former using the shaft as a jig.  As far as the side stringers I'd suggest laminating them against a form from cardboard or foam board so the curve is already present, that way the formers won't try to change position just trying to place a straight stringer on them.  Just a suggestion.

Post by simpleflyer on Aug 13th, 2015 at 1:55pm
You're right, Tom, the more we get into the building of the F-100, the more interesting and enjoyable it becomes.

The stick and former jig begins with a dowel and a punch for punching the former holes.  The first dowel we started with was 5/16 inches in diameter and our punch was 3/8s inch.  This left with a very loose fit between the dowel and stick.  So we tried to take up the loose fit with wrapping paper around the dowel, but this proved to cumbersome to work with on the F-100 due to the long fuselage.  The rolled paper might work on smaller/shorter fuselages.

We were able to find a 3/8 inch diameter dowel in our supplies and it works much better.  We cut a strip of paper and mark the former locations to the strip and tape it to the dowel and slide the formers in place.

The primary parts of the simplified stick jig system.  A stick and a punch that will provide a stick and former fit that will allow suitable movement along the stick.  A few temporary retainer formers to hold the stick and formers in place while being glued.

Nose section core structure is glued together.  Some kits have a similar structure where a starting core is formed by the formers and four main wider stringers located at the top and bottom and both sides of the fuselage.

Rest of the core fuselage nearly all glued up.  Nextis to cut out a piece of main stringer above the horizontal and build a slot to accept a tab on the bottom of the vertical tail that will be located there.

Structure of the F-100 is relatively simple:  Between formers 1 and 4 is the nose section.  Between 4 and 6 is wing section bridged by wing mounting platforms, the cross-strip shows location of one of the wing spars.  6 and 7 is a space between the wing and horizontal tail.  7 and 8 are bridged by horizontal tail mounting platforms, the tail pieces will be attached to a 3/32 dowels passing thru them.  8 to 9 are the end of the fuselage.

Great job so far!  I think you were wise using the smaller diameter dowel!  This is going to be a good looking model....I know I've don a 100 before but I think a bit larger model with a 16" span might be called for!  Like what I'm seeing! [smiley=thumbsup.gif]

Thanks for the comment, Tom.  Assembled the vertical tail, today and added some 1/16 strips to the fuselage.  Had a minor mishap when trying to sand a notch in one of the assembled formers.  I was holding the former a bit firmly while sanding and the former broke, managed to glue the break together and reinforce the the repair with a bit of tissue and glue.  That soft light  balsa that we commented upon earlier is a tad fragile. 

Starting to cool a bit so we took an Avenger built a while back for a bit of flying this morning.

Wing construction is a bit of a challenge.  We had been toying with the idea of making the wings removable.  And when we got to this point, we decided to go for it.

The first step was to install two stronger stub spars at the inner rib area.  The forward one is 1/8 by 3/16 and the rear one is 1/8 square bass wood.

Next we built two balsa boxes for the stub spars to go into.  The length of the boxes is the width of the fuselage at the wing mounting plates.  The boxes will fit into the 2   notches cut in the wing plate.  One box has 4 sides as it will go into the square notch.  The 3 sided box will go into the rectangular notch and be glued to a former at that location forming the 4th side of the box.

The last time I was there they had a C-130 drone control aircraft with two drones under the wings... dayglo orange. 

The F-106's were drones also.  There were alot of private warbirds/jets there as well.  A Hunter, T33's, Even a couple of P-3's.  Lots to see and when we went to the Airport office we made arrangements for a tour of the place that was very nice and not too expensive.  Got to see the stored airliners that were mothballed there.

This fall has become a rather busy time with a lot of household chores and other activities with our extended family.  So our model building and flying activities have slowed down.

The F-100 project has been shelved for a while until things slow down a bit.

We did have the opportunity to build the Berkeley Profile Powerhouse for the Berkeley cook-up.

The Powerhouse is pictured here along with a couple of flight pix.  We used an old Cox 020 TD given to us by a friend for a nose weight for the model which was modified to be flown as a 'swinger'. 

Looking over our modest stash of Cox PeeWees and remembering our control-line experiences of our childhood got me thinking about starting a thread about flying control-line models as 'swingers'

Next the modified enlarged Cloud-Buster.  Note the relationship of the swing line to the wing tip to which it is attached.  These CB swingers are good flyers and when they encounter sudden gusts they take some unusual flight paths.  A neat way to observe the effect of relative wind(air).

.....what happened next.
  Interestingly, nothing much - the plane just sorta flew on its own a bit and when the line tightened up again it returned to its circular flight path.  Most of the bigger and lighter swingers are just gliders trimmed for straight and level flight, and that is what they return to when the swinging force stops at their wingtip.

Here's a picture taken today of the SS-40(a 40 inch swinger).  It recovered nicely from a gust.

Another 'old timer' flown on Sunday, was the 'Super Cloud Buster'.  This was one of our first scratch built original swingers.  We used the dimensions of the Cloud Buster as a building guide.  It had a heftier nose pod than the Cloud-Buster with a nose wheel and a polyhedral wing attached with a rubber band.  Looking for pictures of when it was built, we were surprised to find that the model will soon be seven years old.  Here are pictures of it when built.

Sunday, Norma's  grand-niece and grand-nephew came over for lunch and a visit.  Norma got around to showing them my 'toys'.  They showed some interest, so we took them to the back yard for some 'show and tell'.  Here's Rommel making his first flight with the CloudBuster 2 with a Flyboy wing.  He thought that it was 'cool'.  He's a research technician doing work on renewable energy so I mentioned to him that swing control is an application of renewable energy, the models are largely environmentally friendly and no noise pollution [smiley=thumbsup.gif]

After a couple of busy weeks and a couple o heavy rains, we were blessed with a beautiful day with blue sky and light winds.  So we decided to celebrated today, the 112th anniversary of the Wright Brothers flights at Kitty Hawk by flying a trio of our favorite 'swingers'; our original CloudBuster, SS-24 with the Jr Powerhouse wing, and the SimpleSwinger with the 40 inch wing.

Here are some pix of celebration.  Enjoy,

Thank you, Tom, for your comment.  These few sunny days have been a treat.  They follow about a week of rainy weather that has left our back yard and fence as the pix below show.  And the next ten day forecast promises more thundershowers with one partly cloudy day on Christmas Eve.  So I guess flying opportunities will be curtailed.

This past winter has been busy with holiday activities and birthdays.  Mild weather has allowed us to start a lot of early yard work and garden activities, plus work on our back yard drainage project.  Topped off with the dreaded filing of the income tax form.

The building of model has been curtailed as well their building.

However, today was a warm, cloudy, and not too windy day so we took the opportunity to do some flying.  So here are some flight pix of the Simple Swinger 16, a profile P-40 and Yak 15.

Thank you, Tom and Bob for your comments.  These 'swingers' are a joy to fly and we try to have a backyard flying session every chance the weather and time permits.  The simple S-n-T scale flyers and the 'simple swinger' series are special favorites because they are quick to build, fly well, durable, and look good in the air.  There is something about sticks and tissue with a skyscape in the background.

The picture below shows today's progress with our back yard drainage project.  Improvement of the board walk and concrete walkway at the back gate.

I can commiserate with you Al... I had to dig some ditches and build a berm to divert water coming off our street right into our carport and under the house.  Part of the downside of living at the bottom of a hill and the storm drain getting blocked so all the water came over the street and into our carport.  But after getting a ditch dug and the berm made across the driveway, the house has stayed dry for the remainder of winter.  Hope your project turns out as successful as mine did.

The drainage  project is related to the 2 pix shown in reply #517 on 12-18-15.  They were taken a few days after some heavy rains this past December.

On warm spring-like days in Jan and Feb, we deepened some existing ditches and built up a walkway between the back fence and the ditch running along the back of our property.  We made up some mats out of old fence pickets to allow work around the ditch.  The soil in that area is black gumbo and doesn't dry out until the dry days of spring arrive.

During the middle of last week we had a couple of days of heavy rain.  On the day after an especially heavy night rain.  Our back yard looked like this.  The water was enough to dislocate sections of the board walk.

A couple of days later the water had receded into the newly dug backyard ditches and the outside ditch receded and the raised walkway along the fence was usable and the pool pictured in reply #517 was lower and somewhat smaller.

When the ground gets a bit drier, I shall need to start scraping up some more dirt and start filling in the pool.  That will be my spring-summer-fall task. [smiley=thumbsup.gif]

In spite of the frequent rains the backyard drainage system works well.  Since the last posted pix the water drained off.  Last Friday a heavy rain filled the ditches again.  Yesterday, they drained off as the pix below show.  And this afternoon they are gathering water and if the next two day's rain forecasts are correct the ditches will be full again. :-/

Being a fairly nice afternoon, we decided to do a bit of flying.  So we took a couple of 'simple swingers' for a bit of air time.  The first 4 pix are the SS-30 with the Phantom Fury wing, last two are the SS-24 with a Jetco Hawk wing.  A nice diversion from all the stuff going on now-a-days.

Thanks for your comment, Tom.  We woke to the sound of rainfall this morning.  After it stopped, we checked our raingage at 1 1/4 inches.  Checked the drainage ditch and it looked as seen below.  At this level, the wooden section adjacent the pad under the gate begins to float.  Next dry spell, I need to raise the wooden section.

Behind the gate is more water.  But it will all drain off, once the rains stop.  Probably will drain faster than the Brazos River. 

A pity about the Soldiers at Ft Hood.  But folks gotta learn 'DON'T DRIVE INTO RISING WATER!  A cardinal unwritten rule of driving in rainy TX weather is 'Turn around - don't drown'.

Latest from WU.

* Forecast... the river was cresting this evening and is expected to begin a very slow fall later tonight or Friday morning. It is believed that the water has been backing up due to construction downstream. This has made stage forecasts that more uncertain.

Hope things are all right Al...been watching the news over the past few days...I think you're being tested.

I've never tried flying an airplane by tether...notice you seem to be using a pole to assist.  Question...how long is the line you're using...and is it managed by letting out as the model builds speed?  Do you weight the outside wingtip...use rudder offset?  Looks like easy fun...brings back the control line days of my childhood.  :)  Very nice models as well....

Best of luck Al, God willin' and the creek don't rise (any further). [smiley=thumbsup.gif]

Title: Re: Tether Flying for S&T models
Post by simpleflyer on Jun 5th, 2016 at 1:06am
Thank you, Neal, for your comments and kind wishes.  The river level continues to decrease at a good rate and the rain is doing the same so things are quickly getting back to normal.

To answer your questions.  For the recent flights we were  using two lengths of line attached to separate poles.  The line lengths were 10 and 20 feet, approximately.  The short line is used when the air is more windy and unpredictable.  Bad flight attitudes can be easily resolved by quickly raising the pole to a vertical position and terminating the flight.  Gentle air allows the use of a longer line for smoother more stable flights at a more normal attitude.  Neither wing tip nor rudder offset is used. 

You mention that it looks like fun.  I'll confirm that, it is fun.  And it is a return to our control line roots, also.  A  long time ago, I started out building a few Comet stick and tissue kits and was getting nowhere in trying to fly them with rubber.  I noticed the sketch posted below on a plan of a Comet F4U that I was building.  I tried it and it worked well.  After that I moved to CL until completing high school.  Then more school, USAF, and a succession of jobs until settling into a career in aviation kept me away from models until a forced early retirement.  Now, I've returned to those simple pleasures of childhood and am enjoying every minute of it.  If I may, allow me to suggest to you the browsing thru some of the first pages of this thread to see how we evolved in our activity of swing control.  Enjoy,

Al

I must have seen that Comet flying instruction a million times and paid it no mind.  Thought I knew is all.  ;D  Come to think of it...I have flown tether once as a kid...had one of those Wen-Mac airplanes I could rarely get the engine started.  I remember swinging it in disgust on a line...a bit like trying to fly a brick via centrifugal force! ;D

I'll check thinks out.  Looks like you're having fun and that's what counts in this hobby.

Thank you, Neal, for your comments, especially about swing control.  Truly, its simplicity allows this form of model flight to be overlooked.  But it does offer a lot of benefits and enjoyment.  We've been enjoying it for several years and hope to for many more.  Only, currently things are very busy and we are not building and flying as often as we would like.

A few weeks ago, we posted some pictures of our continuing progress with our backyard flying field and they disappeared.  So here is a re-post of some of them. 

The first two show the removal of a couple of stumps that were remains of obstructions to the field. 

The last two are the felling of tree that had been struck by lightning some time back, and was a possibility of falling on our back fence if it had been left to rot and fall on its own.

I've had a similar thought several times, Tom.  I think it could be done with a ROW free flight model with a good water proof finish.

We were able to get to our paved path to the back gate on Friday and found our wooden bridge had washed out again.

Yesterday, we fished the boards out to higher ground and made a temporary path to the gate out of planks.  We were able to check out the water in the ditch and it was pretty full.  This will take a while to drain off.

As soon as we can, the wood bridge will be replaced with concrete blocks and bricks.

First was a 'Simple Swinger' fuse with the horizontal tail of a Cleveland Condor as the wing.

Thank you for your kind comment, Tom.  The weather is  pretty nice now, except for some strong winds now and then.  This should help in drying out the back yard.  We were able to start replacing the washed out foot-bridge to the the back gate, today.  Slight chance of shower tonight and then several days without rain.  So a new bridge should soon be in place.  Overall, the weather is pretty good so far.  Thankfully, no severe bad weather.

Early in the week we obtained some hollow concrete blocks and concrete bricks for the bridge replacement.

First, four of the hollow blocks were placed in the middle of the ditch with the hollow openings adjacent to each other.  The row of blocks now become a pair of square culverts to allow the water to pass thru.

Next, we put some soil between the existing walkway and the hollow blocks.  Concrete bricks are added to the walkway and it will be extended til it reaches the bricks at the bottom of the gate.

Uh, not really.  We did have the opportunity to fuel some of their aircraft over the years.  We were a 'Brown-builder' employed by Brown & Root.  Never built anything, but fueled and hangared a lot of airplanes and associated tasks for almost 18 years.

The bridge project is coming along nicely.  The bricks are in place over the hollow block culverts.  The source of the fill-dirt used will be converted to flower and veggie beds for Norma when warmer weather arrives ;)

It's hard to believe that spring is almost here and our building and flying of the 'swingers' has slowed down so much.  Age and household tasks are taking up more and more of our fun time with the 'swingers'.  This afternoon was so beautiful that we had to go out and do some flying  and take some pictures.  So we took the pole with a short line and a few profile models out to the backyard and went for it :)

First up was the profile Air Tractor 402.

As a 'swinger' it is a good flyer and has rewarded us with many good flights.  If we can steal more time from  'yardwork', we shall try to add more to the QuarterA swinger thread.

It is nice to see sunlight and warm temps, but the green things begin to become active and need tending and past projects need attention.

With the help of a relative's electric chain saw, a stump was shortened to hasten its removal.

While the power saw was available, trunks of a couple tropical trees frozen by a freeze last December were removed.  The trees became a nuisance with their fast growth and production of so many leaves and seed pods.  These together with our neighbors Pecan trees kept me raking and hauling leaves more than we were able to keep up with.  So, when they froze, it was decided to make them 'history'  [smiley=wink.gif]

Today was a great day for flying - clear, crisp, a bit of wind but manageable for a short line.

Start off with a couple shots of the Guillows '1/4-A' Starfire glider.

Thanks, Tom, for your thoughtful comments.  We've had success with the profile A-26 - built two of them so far - and plan to explore the design further, like an Onmark Tradesman with a nose mounted 1/4-A and the wing nacelles removed :o

Also flew the profile Monarch 26 model and a swinger of Bob Hoovers 'ole yaller' to finish this mornings flight session.

[quote I was reviewing the previous pics and the thought occurred to me that your B-26 might make a great catapult glider!][/quote]

You're right, Tom, the simple efficient design of the A-26 translates to stable good flying models.  The design is largely the work of Ted Smith, who was in Ed Heinemann's engineering team at Douglas that designed the craft.  Ted went on to design other fine flying aircraft:  Aero Commander series, Jet Commander(aka IAI WestWind}, and Aero Star.  All are fine flying and well performing aircraft.

One of our favorite A-26 variants is the Tempo family developed by L.B. Smth(don't know if he and Ted were related).  His start with Tempo was a modification named the Super-26 illustrated below.

Our next swinger will be a kinda 'what if' model of the Super-26.  Suppose if RA Smith had decided to build a single engine version of the Super-26?  We ran the above drawing thru MSPaint and removed the wing engines and relocated one onto the nose.  Something akin to pulling the R-2800s and hanging a R-3350 on the nose.  Saw a profile drawing depicting an OnMark with 2 wing mounted R-3350s(someone was considering such combination for air racing-don't know if it materialized.)

Our model will be simple profile 1/4-A swinger.

Had the priveledge of see Bob Hoover do his thing at an Airshow in So. CA  one year many moons ago.  He flew both old yellar and the Aero Commander.  Absolutely amazing to see his routine with the Aero Commander.  I knew the P-51 could do all those things but the Commander was a true surprise!  and the energy management routine at the end with both engines shut down was a mind blower.  A truly talented and gifted pilot!  Thanks for the memories.

This new model reminds me of a small civil aircraft but with similar lines...the Grumman Hustler 500

Thank you, Tom for sharing your recollections of seeing Bob Hoover's routines in the Shrike Commander.  You are right, they were a wonder to behold.  We too, were privileged to see him fly the Shrike Commander - twice; once at Riverside Airport near Tulsa, OK - again at the Confederate AF Airshow at Harlingen, TX.  Both were amazing experiences that I shall remember always.

We were anxious to try how the single engine version of the Super-26 might fly.  So we pulled the wing nacelles off our Monarch-26 and changed the nose weights a tad.  Looked like it should work well.  Went   into back yard and gave it a few swings.  As expected, it flew well.  Now to draw up some patterns and start cutting wood for the 'quarter-A' version.  BTW, thanks for the Hustler image, nice looking craft.

Thanks Al,
It's fun to reminisce from time to time.  The Hustler looks like a nice swing or rubber powered model.  Especially the 500 version that had a jet in the tail as well.  Turbo prop and jet would have been quit a performer.  I don't think it made if beyond prototype or drawing board.

To prepare for the construction of the Super-26, We took the 2-view drawing in post #587 and edited it into a rectangular shaped file as posted below. The image contains the shapes of the Super-26 in an arrangement that can be printed to a legal sized sheet of paper.

We used the above posted image and printed it to two legal sized sheets, one plain paper, the other to legal size card stock cut from a legal size file folder. 

The plain paper copy is marked up to show what changes need to be made to original plan view to make the patterns to cut out the parts and how to assemble them to make the model.  The flying surface location and angles are drawn.  The wing shape was changed a bit and enlarged.  Using this data, the parts are cut from the card copy.

Thank you, Tom, for the 3-view of the Hustler 500.  You've convinced me to make a quarter-A profile swinger of the Hustler, next.  Here is my pattern  file that I made from your 3-view.  Wing shape has been modified and a longer wing will be used, about 24 inches.  It looks like it should be a good flyer.

This past Saturday, Houston IPMS had their ModelMania 2017.  I rented a vendor table and Norma and I attended the event to sell some old plastic models.  We brought over 210 models and were able to sell over 60 of them.  This is how I earn by 'hobby money' [smiley=thumbsup.gif] for future purchases.  It was an enjoyable day and were able to meet with several old friends that I have met in the IPMS community over the past years.  Norma took a few pix.

Plastic are not all of the models at these sales.  Over the years we have often found a few wood models.  This year we found these.  The Comet Zero and Guilows  FW-190 we part of estate sale by a group of vendors across the aisle from us.  We obtained them for $5 each.  The Monogram P-51 and Strombecker F7U were obtained from fellow vendor who traded them for one of my plastic kits and a few $s extra.  The Comet and Guillows will be listed on the forum for sale threads on the internet in the future.  I'll list them on SnT before going to other forums.

See posts have been quiet for some time now. It's a shame more people do not enjoy this hobby. It is just so easy to enjoy. Been very busy lately in life, and have flown RC very little this year. But I always seem to find a little time, to squeeze in some teather flying. Whenever the urge hits, I just walk out the back door, and I'm flying. Plus, I still have all my teather airplanes in perfect condition. There is never any crashes/wrecks/repair issues. And, the exercise I get in my arms is welcomed. From sitting at a confuser all day, it takes those knots out of my back muscles. Wishing more people, would give this hobby a chance.

Thank you, Dave, for your kind and informative post.  I apologize for not having responded sooner.  We're beginning to experience some aging issues like vision impairment and increasing joint aches so our activity level is slowing down a lot, especially model airplanes.  Plus the frequency of household chores is raidly increasing.  The close encounter with hurricane Harvey had our attention for a while but we survived the event with no ill effects.

So, after a long break, we are going to try and get back into the 'swing' of things ;)  The advantages of swing control that you describe are true.  It is simple, affordable, and easy model airplane activity that offers a lot of satisfaction and enjoyment.

Today was a beautiful fall day, just right for flying so we decided to take advantage of it and return to flying with a trio of our favorite swingers.

This time the enlarged modified Cloudbuster fuselage is attached to a Berkeley profile Powerhouse wing.  The 24 inch Powerhouse was designed for Cox 020 power.  This wing with the Cloudbuster fuselage results in a solid stable flying combination.  The trio of models gave us a fine model flying experience this afternoon.

After a rainy morning, the afternoon settled enough for a short flight session.  The front had passed through and we were left with light breezes and scattering clouds.  Our swinger this time was the SS-40 connected to a suitable fuselage.  It had been some time since last flying the SS-40 and I discovered that it's original fuselage is awaiting a rebuild.  The substitute fuselage flew well and a good flight was enjoyed.

The SS-40 wing is much modified Comet Meteor wing extended out to 40 inches wingspan.  Meteor wing is the same as the Comet Cloudbuster and Guillows Flyboy.  Construction description may be found at - http://www.stickandtissue.com/cgi-bin/yabb2/YaBB.pl?num=1273164221/413

Thank you, Richard, for your kind comment.  I'm glad that you like the picture.  For these close up shots, I cheat a little ;) and use a short line on the swing pole.  However,  the lengthened Meteor wing loves to fly on any length line.

By the way, I appreciated and enjoyed your pictures  and information about the wild-fires and the aerial equipment used to try to control them.  I am impressed and a big fan of the Air Tractor 802U, a versatile and very capable aircraft.

Hi Al - to tell you the truth, I cheat on my pictures also.  ::)    I launch the plane and then try to run to the other side of the Cricket Wicket, to be in position for when the plane completes a one half circle, to take the pic   :D  as it flies close by me ...  ;D  but it works!  LOL
Al, those fires out west are still burning and the Vineyards of California are also ablaze ... 
I also really like that Air Tractor "FIRE BOSS"  Fire Boss - AT-802F  water bomber, with 5 prop blades, which utilizes Wipaire 10000 amphibious floats, so that it can land on a traditional runway or on water. The Fire Boss can scoop water with these Wipaire Floats from a lake OR river for use on a fire.  If you ever hear of a plan or a kit of this water bomber, please let me know - it is at or near the top of my long "to do" list of interesting planes to build.
    Your SS40 does have a really long wing, and a quick glance almost caused me to guess it to be somewhat resembling the Swiss made "Solar Impulse" solar powered aircraft that flew around the world.
     Tether flying does look like fun, but I have never tried it ... :(

We repaired the nose section of the original fuselage of the SS-40.  A piece of wood was replaced at the slotted end.  The nose was changed to use a Cox 020 nose weight.  A new member to our Quarter-A fleet of swingers.

In the original nose section three holes were drilled lengthways in the front of the section and were filled with lead shot and a streamlined removable nose was constructed and attached to front.

In the 'quarter-A' nose weight system, finishing nails are inserted into two of the holes.  A dowel is inserted in the remaining hole and a C0x 020 core(glow head, cylinder, crankcase) is slid onto the dowel.  The dowel is shaped to have a tight fit with the fuselage and the Cox core.

The quarer-A  SS-40 in flight in the back yard.

Several years ago, I had envisioned flying 020 powered pylon models in the back yard under their own power.  But, by using a fish pole and some line, and doing some hocus pocus with the flight forces, I can experience this activity in an easier and simpler fashion, without the noise, expense, and tinkering with an engine.  It doesn't  get any better than this :D

The conversion consists of removing the tank assembly and the moving parts from the cylinder/crankcase assembly.  The crankshaft is about 1/8 inch in diameter.  The allow one to use 1/8 square wood stock for mounting the weights to the model.  A very easy to build installation and easy to maintain.

Hi Al - those are neat little engines.  [smiley=thumbsup.gif]   I made a balsa pontoon boat when I was a kid, and used two Cox .049 engines from control line flying, as pushers - one engine over each pontoon at the back.  Me and my buddy would go to this pond at the park, him on one side, and me on the other, and keep sending it back and forth to each other - and refueling while both motors were still running ...

Yep, simple as dirt, and cheap, easy to do, quiet, and can be done in any airspace that can contain the diameter of your swung circle.  Primary requirement is a stable model trimmed to fly straight and level.  I prefer models with lower wing loadings, they seem to fly better for me.

     I love those GREAT, close up in-flight pics too Al !! [smiley=thumbsup.gif]  :D 8-)  Hey Al, coincidentally, and strangely enough, my   17 3/4"   wingspan Guillow "Cloudbuster" has a very similar color scheme to your Cloudbuster.  My rubber powered, stick fuse Cloudbuster - in the summer of 2014 - used to try to fly right out of Jackson Park - WAY up too high, and GONE with the wind - fly into Windsor Stadium and fences and get stuck way high up in the top canopy of trees.  No wonder they call them "Cloudbusters" !!   And I was just finger winding back then!
     We have a five inch dump of snow now at 11:00 PM Monday Dec 11 2017, and it is still coming down over here in the Windsor/Detroit area.

Thanks, Richard.  Your Cloudbuster looks good and I'm happy it flies well for you.  It's an interesting coincidence about the tissue color schemes.  Our tissue scheme was simply accidental.  I had some scrap red and blue tissue and used it to replace torn panels as they happened.  The Air Tractor and P-40 need some finishing touches which hopefully will be done someday.

Yesterday, we received a visit of the white icy stuff, again..  The past weekend was almost warm.  Then, freezing temp with light freezing showers arrived before noon and continued to dark,the temp continued to drop to below twenty degrees overnight and did not get over the freezing mark until almost noon today.  However, the skies cleared and it warmed up to a tad above 40 degrees.  Tonight, freezing temps arrived again, predicted to drop to about 25 degrees before leaving us about mid-morning, tomorrow.  I will be glad to see the freezing temps go away.

First pic shows the neighborhood yesterday afternoon.  Next pic is Norma's car this morning.

Last three pics are the Simple-Swinger S-40 and the profile A-26 as we tried to take advantage of the nice afternoon weather, but kinda cold.

In our last post about a week and a half ago, we showed  some of the Cloudbuster family quarter-swingers in flight.  It was so much fun we decided combine the two and and to the fleet.  We'll start by adding PeeWees to the noses of the SupeCloudBuster and the Droop Snoot.

The   picture shows a few of the Cloudbuster family.  From bottom to top:  our first Cloudbuster modified to swing control, actually a Comet FlyBoy.  2nd is a scratch built highly modified swinger based on the AirBoy/Cloudbuster that we named the Super Cloudbuster.  3rd is scratch built modified CB with a rib set from a Comet AirBoy and a scratch fuselage.  At the top is Droop Snoot.  Scratch built-up sheet balsa fuselage.  Tail and wing surfaces based on the Jetco Lark with wing ribs from a Lark.

A front view showing various nose weight installations that we've used over the years.

Left to right.  The first modified Cloudbuster had a laminated nose section with a narrow open box into which clay could be inserted. 

The Super Clloudbuster originally had a box in the nose for clay, but was closed over with balsa, and replaced with a bolt and nuts.

The second modified Cloudbuster had a laminated nose section.  A cavity was cut in the center section and filled withe needed lead shot before the side pieces were glued in place.

The Droop Snoot has bold and nuts fitted to the nose for a balance weight.

The Berkeley Profile Powerhouse on the end has a worn out 020 TeeDee installed for a nose weight.  The  020 is being the nose weight of choice for much of our current models [smiley=thumbsup.gif]

Only the glo-head, cylinder, and crankcase of the engine are used for the noseweight.  These provide enough weight for most of our quarter-A installations so far.  Not using the crankshaft and interior parts make the installation of the engine easier and allows it to be easily changed from model to model. 

To complete the installation, a1/8 is punched into the nose. (we use piece 1/8 brass tubing sharpen at the end) The hole is deep enough to accept a wooden dowel that will be used to connect the engine to the model.  The crankshaft of Pee Wee appears to be very nearly 1/8 inch.  Using a slightly oversize wooden dowel tightly fitted into the 020 crankcase.  Excess dowel is cut off to allow a small part to at the front end.  At the back end enough dowel is left to be inserted into the fuselage.   So far about  na inch and a half seems long enough.  The key of this installation depends on a tight friction fit between the engine, dowel, and fuselage.  If any looseness is found in the installation, we wrap a scrap of paper around the dowel in that area to increase the tightness of the fit.

Another day of blue sky, light breezes, and light variable wind.  Just right to check out a couple different wing combinations on Droop Snoot and the Super CloudBuster.

1 & 2  -  Droop Snoot with the Berkeley Powerhouse wing.

3 & 4  Super CloudBuster with a Guillows Javelin.

Al - I have a dumb question - how much fuel do you put in them and how long, and how many laps, do they fly for ?

Well, since you are turning in a circle, it isn't too healthy to take on too much (alcohol-based) fuel because you get dizzy enough just keeping the plane in the air without extra help.  ;D

Dizzy is right Ian.  My record at 15 yrs old in my High School Flying Club after school is 46 laps.   ::)

This is one of Al's videos previously posted:  https://www.youtube.com/watch?v=JnT2nA6NO9g&feature=youtu.be ;  of him flying a delta dart.

Hi Al - I mean the bigger tether flyers with engines.  "How much fuel do you put in them and how long, and how many laps, do they fly for ?"  I haven't flown a fuel engine model in 46 years.   :)  I guess you just fly until the fuel runs out ...  Do you have a link to a couple of videos?

Thank you, Richard, Ian, Tom, for your kind posts.  Excuse us for not responding to them earlier,  we're having nice warmer weather so we've been busy with yard work and other tasks and have neglected to keep up with the posts here. 

To answer your questions, Richard, although the models have a Cox 020 attached to the nose.  It is not used as power for the model.  It is simply a nose weight to help in the balance the model.  However, it does have the appearance of Ukie model in flilght.   

In the Control Line section of this forum, I have a thread  about QuarterA Ukies which explains more about this form of model
http://www.stickandtissue.com/cgi-bin/yabb2/YaBB.pl?num=1471843717/0

Thank you,Tom, for posting video of my flying the Delta Dart.  In this flight the swing pole is pointed upwards and swung so that the model flies in circles above my head.  In another flight pattern the model is swung into the air and the pole is extended in front of me close to parallel with the ground and the pole tip  is moved in small circles.  This causes the model  to fly in a circular path in front of me.  Using a swing line shorter than the swing pole, contact is avoided between the swinger and the model when the models path comes close to the swinger.  This video shows a flight in this manner.

Here are a couple of videos with me turning in circles with the model.  We very rarely do this any more, at a  ripe ole age of 78, we try not to engage in risky behavior that could cause a fall [smiley=cry.gif]

Hi Al.  Thanks so much for all the video links and stories.  Very educational.  You obviously had a lot of fun in your life with aeromodelling.  It really cleared up a lot for me.   [smiley=thumbsup.gif] Now I know that half A size is .049 cu in, and quarter A size is .020 cu in engine.    :-/    The article about the intro of the .020 engine stated that it had a lot of power.  I built a 30" Aeronca and put that .020 engine in it for U Control (Ukie), and the other kids in our Gr 9 Model Flying Club in High School said it would never fly - but IT DID !!!   ;)    I also made a twin hull Catamaran boat with two Cox .049 pusher props and SHE really went!   You really have a great collection of little engines there.   Again thanks for all the videos - great loops by the way!  And Happy Flying!

After flying Droop Snoot with the 020 in the nose we kinda liked the illusion of flying a model from a long time ago.  However, the models flight pattern was not as smooth as before.  The 020 installation did not have the weight that had been used before.

Rather than add more weight to the nose, we decided to remove some weight from the rear of the model, and see what would happen.  We selected an area shown by the red line and cut it off with a fine tooth saw.

The cutting operation went well.  Only needed a bit of sanding to smooth of some rough edges.  Now to glue a bit of tissue to cover the bottom of the fuselage.

Al, I like the shape of this fuselage. Cannot wait to see it finished and in flight.

The fuselage bottom is covered and Droop Snoot is ready to fly with more droop. [smiley=thumbsup.gif]

Thanks, Bob, I kinda like it, also.  I'm planning to build a version II pretty soon.  Here are a few flight pix.  The first is with its original wing.  The other two are with the Berkeley Powerhouse wing.

Sweet...I like both wings but am partial to the polyhedral wing with the raised tips!!

Thanks for your comment, Tom.  The polyhedral wing is also our favorite.  We're planning to put a longer polyhedral wing on a future version of the Droop Snoot.

Just got word down the chain of Al's health downturn.   His wife Norma shared with Bob that he's had and incident that has effected his speech, mental activity and arm.  The doctors diagnose him with "Altered Mental Status",  the other doctor diagnosed him with "Acute Vascular Dimentia".  We'd like to ask our members to remember Norma and Al in their thought and prayers.
