Whe had the same feeling, it could have been a very long walk to retrieve her, but al of a sudden she turned.

After that flight I broke her wing for the second time and had to make a new wing.

Luckely she still fly’s

Still need to trim a bit more but I am waiting on smaller rubber

And now with a little more downtrust

Spliffsecond... had the photo problem a while back when Photobucket went from free to charge.  It was a real pain. 

You could restart the SE5a build again and delete the old one.  I know that's a drag...as you said, the "Modify" button is only available for about 15 minutes after your original post.

I will go with gurney strips then, I already use them on the CLG's

Any idea's on rubber and motor?

I was totally unfamiliar with the height the plane would reach,
my other CLG's do not perform that well. If I had known I would not have tryed it there.

I cannot change the URL's of my images in older posts, the option modify seems to vanish after a few day's. This makes my topic of building the Se5a rather useless.   Sad

Spliffsecond,
Great inspiration.  You mentioned trying a flap on the right wing.  Some of the fellas are using "Gurney strips" 1/16" sq. balsa strip approx 1" long to start with instead of plastic that can lose it deflection from flight to flight.  Add or subtract from the strip as needed with an xacto knife.  You can do this on the elevator too.

Hi gentleman,

I have noticed that my image storage provider changed URL's and all my photo's are gone from my topics, I will arrange that when I find time.

I had lost fate in the piper when after the last posted flight's I went out two times and had no luck at all at repeating what I had.

After carefull inspection I finally found the stab to be skewed and twisted ever the slightliest. So I made a new stab I removed all previous trimming and remade the broken struds, glued the wing, I had broken while I stumbled in the field  Roll Eyes and look now

https://youtu.be/lqR4gpWEEb4

This is 600 turns on a 12" loop of 3/16" tan rubber,
I also like my new flying field, it's a bit masochistic with all the trees, but they give a nice cover for wind.

https://youtu.be/GpmPVmFniW4

this is  a bad launch with 700 turns

https://youtu.be/7b8KIhEC8uc

and this is the rest of the turns, I like her slow stable flightpath

https://youtu.be/FKdhJbrIOhQ

this is a good flight with 700 turns, I think she hit a branch because all of a sudden she spirals in.

the only trimming I had to do was a little clay on the right wingtip to make a tighter turn. Since I made a 1mm triplex nose mount I didn't even had to add balast to the nose, she just balanced perfectly. I made the stab out of very light 0,8 mm balsa. I used shellac to seal the stab so he could not warp again.

Now I need to get my flight time up, what do you guy's suggest?
I was thinking along the lines of :
A little up elevator for higher climb
Replace the (heavy) clay on the right wing by a mylar trim tab
New motor configuration.
I have no clue here so it would be nice to hear something about the size motor I can put in this 16" span. It turns a 6" peck propellor (straight out of the package, not balanced)
By the way I only have 3/16" rubber at the moment, I would like to buy some more rubber but am a bit lost as to what I will need.

If there is another calm day like this, I am starting to feel confidend enough to try my SE5a again.

I also made a new CLG, a lawn darty it came out with a 7 1/2 " wingspan instead of the intended 8" because I fudged the printing of the plan.

https://youtu.be/XahbjSgY35E

It needs some trimming, but I was not prepared for such performance. What a difference a bit of airfoil makes  Shocked
It was still a bit windy and I need to balance the glide a bit more.
Then we had the chance to play, spot the airplane in the tree canopy for half an hour  Grin and then the fun of shaking it out of the tree.
I made some other flights but my camera operator was unable to spot the tiny glider. And after another tree removal we called it a day. I will try the Lawn Dart at a bigger field, it will be fun.

Maybe adding a little down thrust would help prevent stalls during the initial power burst as you increase turns on the motor.

Went out today, the wind was calm at 8 km per hour.

They have plowed my flying field  Angry

So I had to go to a smaller field.

Some in flight foto's

...

...

...

...

I have 3 videos of flights and they get better and better.

First flight is 500 turns on a 12" loop of 3/16" F.A.I. Tan Flight Rubber.

https://youtu.be/QSateTX-W88

second flight is 600 turns with less downtrust and a little up elevator.

https://youtu.be/amMiDeX0NZE

tirth flight is 700 turns, but the weather changed rapidly and the wind picked up violently. You see her struggeling. I can only imagine what this flight would have been 10 minutes before with no wind.

https://youtu.be/qgBrYBMngKA

But tomorrow the predict a good day with very little wind.

If with what you see, you have any tips for me, let me know.
I am convinced that with some trimming, she might fly 1 minute and more

Until then ...

It's really true, tall grass really does exist. I like it when these simple planes work so well and yours is no exception. Looking forward to more flights.

So second time,

the candidates for flight

...

the field

...

the flying

...

...

The piper behaved much better than last time, still not perfect and a little bit all over the place (no two flights with the same pattern)
After a few flights with 300 turns I broke the nose mount (again)
so back to the repairstation.

I have a video, but it's not the best flight.

https://youtu.be/RISYTJwYryQ

and I also managed to break the wing on the okha.
So all in all not a bad day  Grin

...

Untill next time

No need to thank me, it’s my pleasure.
I wil try to have better footage next time.

Thank you richard for the advise to purchase a flying kit.
But I think I already have all that I need.
I have a laser cut cloud tramp, should be a great flyer and not to much construction.
I also invested in some wood and raided the website for plans, so
I am cutting wood for a chilton DW 16” by clive Gamble and will try to make it really traditional only wood and real dope on tissue, no paint.
I wil also make another printwood kit this time from kielkraft P51,
I know that wwII fighters are not easy flyers but I kind of like the desing simplicity of the kit.
I also like the catapult launched gliders so I printed the plans to an
Fling-Hi G-12 wich seems a nice follow up to the ohka, and seems a good flyer.
Many other ideas in my head ( wakefield, rc conversion, ....) but I have to remind myself baby steps.
So, I do appreciate your advice and would follow it but I already chose another path.
I will however not trow the Se5a in oblivion, but she will fly eventually, when I got enough experience.
I will not give up if I don’t succeed at first, I ‘m rather stubborn.
Thanks again.
Untill next time.

Hi Free - thanks for the videos - nice to see someone go out and actually try to fly.  Smiley Smiley  You are much more than ready for a
REAL
flyer.  Please don't wreck your nice  SE5a  right away.  I would suggest building a laser cut kit (no die crushed balsa kits and no printwood kits),  that is
guaranteed
to fly right off your building board and right off the table.  That is Sig Mfg. ( who were the first to laser cut kits by the way).  And they have kits for sale from dealers in Austria Germany Denmark and Switzerland.  I am talking about the  22"  wingspan Sig
"Cabinaire"
.  They guarantee that they will fly for 10 to 25 seconds by finger winding, and fly for 20 - 50 seconds by stretch winding the rubber motor in a winding stooge.  I have had many, many happy flights with mine, my longest flight of  57  seconds.   Here is the link https://sigmfg.com/  And click on Aircraft, then Sig free flight kits.  Good luck on your next flying session!   Cheesy

Good evening gentleman,

Instead of working on the Se5a this afternoon, I went out with the piper and the ohka. Perfect first day of springtime, very gentle breeze and sunny albeit cold.

Since I did not make a stooge yet I had to improvise,

...

...

it works a charm altough I would not reccomend it with more elaborate planes.

The piper flew right away, but now I need to learn how to trim an aeroplane. I did not try and change anything for today I just wanted to see what she was dooing.
After a few "flights" the wingsupport struds broke and I need to make the motor mount more sturdy. But in general I am very happy.
I had to stop trying because she took a bath in the only ditch in the field

...

Almost ok flight, I think she needs a bit of up elevator

https://youtu.be/PeNVEg7DdKU

And the reason you should not try to launch a model and film at the same time. I launched her into a stall, but she really wants to fly.

https://youtu.be/H472X11Gjxc



After that it was time for the ohka,
She still went into a loop with power launches and lost the moving portions of the rudder and stabiliser. But even then she glides nicely when hand launched.

...

I was about to give up on her, blame it on the novice builder  Smiley
But then I remembered that I am a lefty and meaby if I launched righthanded it would work?

and ....


Yes, that was all that was needed, change of hand  Cool
Now she needs trimming, but thats for next time because after a few try's I lost the left stab  Shocked and she still flew after that  Cool

https://youtu.be/KKmz_UnBv14

so I went home a happy man and can't wait to get back out there and go for better results.
