Interesting stuff! The guy who checked me on a low-level endorsement showed me what he termed as a `mustering stall` (Aust), where for example, you roll 30+ degrees to the left, boot in more left rudder than required, then simultaneously roll out, and apply more (max) left rudder, giving crossed controls. When it lets go, (at a speed markedly above stall speed) in this instance, it will flip you over in a nasty fashion, and if you leave the ailerons in the same position as at entry, it will enter a spin very rapidly as well. If the power was left on throughout, and assuming the engine hadn`t cut, the ensuing spin had the sweat from your forehead flying the cockpit pretty swiftly. The quickest recovery seemed to be cut the power, push foward, opposite direction rudder, and a modicum of aileron in the same sense as the rudder. The outcome of the initial exercise could never be predicted, but the recovery always worked. Can`t remember alt loss.
