One more thing, i would use Hinge points if you build an FT90, i have seen to many of those things fail at high delflection, another thing get digis, holding power is what you need, and at 3degrees of center they creat maximum torque! Dont put the ball links on the control horn like they say to do in the instructions, thats just plane wrong.....dont ever do that. Another thing, this 'aint' a speed demon, its a 3d demon, so dont fly it like your mustangs or any other plane of that sort, speed is not good(just make sure she stays in the air lol.,@@@!!)
as you have heard, FUN-tana.....
