Here is a good flat spin video. Figured out the sweet spot with this trainer. A slightly aft cg is helpful... along with lots of throw on elevator and rudder ~45deg. Basically I get the model to snap left then with full up elevator and full left rudder allow the plane to do a few tight spirals. Throwing opposite elevator then cutting power flattens it out. Recovery with CG forward is simple neutralize controls and allow the model to come out on it's own after 5-6 spins... with an aft CG you'll require opposite rudder, down elevator, and a whiff of power. In this video we were setting up to do flat spin touch and go's ... so the point was not to recover but to crash.. then take off again.... Darn wet grass made it tough.. there's a short (1.8m) and long video (8m).
