[&o][&o] Buddy of mine is an excellent pilot-- competes in pattern. Has bought two Twists, powered with YS 50 something. Really flies great, till he puts it in an inverted flat spin. The first one was drop dead gorgeaous- almost hovered as it turned. Couldnt get out of the second one-- one dead plane. Second one went down today, same thing-- couldnt get out of an inverted flat spin. Design defect or dumbthumb?
