40% sd extra
I am building a sd/aviation/toc etc 40% extra 260, I Cant find a manual anywhere, Can some one tell me the balance point? Also I am undecided on using 12 hitec 7955 servos or 2 8711(or newer hitec) on aileron and 1 on elevator. Thanks.

RE: 40% sd extra
I am not sure on the factory spec for CG but the center of the wingtube is 6 3/16 back from the leading edge at the tips. I balanced mine at the point for first flight, waiting on snow to melt. Either choice on servos should work. I have 5955's in mine, 2 per wing, 2 rudder, 2 elevators. Will be swapping to 7950's as soon as they are released.
