Default RE: TF Contender 60 build thread.

ORIGINAL: sideng

Has anyone tried programming a little aileron mixed in with the rudder to counteract the roll effect? Does it work, and if so, how much aileron?

I've tried it. Doesn't not work well. If you can add enough aileron to keep it level you find out you also need a considerable amount of up elevator to keep the nose from dropping. Aerodynamically I don't know what the term is, but you have to add so much opposing control surface that the plane gets really wonky. The plane then slows down with all that drag and the forces change and what you programmed for one speed does not work, so the plane starts getting out of whack again and eventually stalls or snaps. I'm going to cut off my straight wingtips some day and try to raised ones. Two friends tried enlarging the bottom of their rudders and that helped but did not even come close to curing the issue.
