Hard, like running full speed(13 mph):black_eyed: into a 10 mph head wind hard throw. It usually flies 50-60 feet, and then yaws right and spins around its vertical axis. The wings are not stalled, I think that I have too large of a vertical surface in front of the center of lift. Would this seem to follow? It also occurs in turns with differential. In fact, differential make it worse!:confused:
