Strokes???? If your talking about throw....I think i have enough at 50deg+. I have never had or seen a thick wing funfly snap. Also i never fly wide open. I have tried at 1/2( witch is where i fly ) low throttle. I have seen some people's snap in one direction and not the other. I have tried left, right, up, down it does the same in all directions.
I have even seen other peoples fun fly look like they snap. But when i fly it , it looks the same but i feel it drive though the snap.
Yes i fly a aft cg too. Dont know what to tell ya.
maybe a snap to me is a real tight snap like in normal wings. But the ones i see in the funflys is the real big barrel type.
