Can someone explain why having a high expo on elevator makes you a candidate for this to happen? I used to instruct full size and used to demonstrate accelerated stalls and accelerated stall spins and I can't get my head around why having a high expo would make any difference, now if what is meant is too much movement on the elevator softened by high expo that is a different matter, its not the expo that has caused the problem, but the excessive elevator deflection, lets not get this confused if that is what is meant.
