Gents,
  Got out with my new Gotcha SX 460 today. This is the perfect plane for my boys to learn on. Within the second flight I was hands off (well kind of) with the 6 and 12 year old. Only one gentle pancake, no damage. I built this with full sized wing and a old Fox .29 for power. Great line tension, about 5 sec. laps. Okay here is my problem, level flight and insides it flies great! Outsides and inverted the outboard tip comes up quite a bit. I know I can heat the covering and twist the wing. For the life of me, I cant remember what way to twist it? Also, why does it not fly tip low when upright?

 No matter what, it was a great successfull day, and the boys can't wait to get out again. I already have to reel them in a bit because they got a taste of their first loops   I really should have taken some pictures

Thanks,
Tom

You just have to imagine that you're flying a real plane and need to use the ailerons of level the wing.

So if it's trying to turn right, you need some left aileron to correct.  On the foamie, it may be assembled a little out of whack, so steaming and heating will only be a temporary fix.  I would suggest making a balsa trim tab and adding it to the outside wing tip.  Without seeing the plane in flight, I'd guess 1/2" x 3" would be a good size for a start.  

Yeah, right, inch, not foot, unless you have a 120" wing.

The advantage of a trim tab is you can tweak it without a heat gun.

Thanks Guys. Yeah LOL!!  I knew what you meant Paul. I'll twist the outboard Wing down a bit and see what happens. I found it to be a little wierd that it flew so well upright but as soon as you start outside manevuers she wants to roll right in.

Thanks,
Tom

Paul hinted at the rest of the problem.

You have two problems to fix.

Warped wing and tip weight.

Your description says that you have insufficient tip weight besides the warp.  Upright the warp is holding the tip down but inverted it is lifting the wing up.  When you get the warp under control either by twisting the wing to remove it or a trim tab to cancel it out then you will be  flying with the wing tip high upright and inverted so before going much farther add some tip weight now.  when the wing is flying the same upright and inverted then adjust the tip weight to level the wings.  I always try to have excess tip weight until I know that the wing flies the same upright and inverted.

I have extra tip weight on my 460.  It cured a lot of strange behavior.  Perhaps an ounce & a half.
