As a swinger it is a great flyer.

But our back yard was not large enough to be a suitable flying area for a rubber powered model of this size, so it was modified to swing control.

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 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:

Simpleflyer was kind enough to share a link to the SFA about tether flying. Havent gotton tru it yet, but working on it. Many interesting craft. Lots of info.
Thanks Simpleflyer.

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.

No engine? 
Yes, please. I would like a copy. Sounds interesting.

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?

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.

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.
Cool Cool Cool Cool
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.
Cool Cool Cool Cool

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!"

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. Grin
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.
