RE: Snaps
Forst, unload the snaps. That is initialt the snap w/ sticks in corners (opposite corners for negative snaps) but immediately pull the elevator out as the model starts to rotate. Secondly, you do need to reduce rudder. I flip to high rate rudder for stall turns.
On the subject of unloading snaps, that technique works extremely well on SA models. It doesnt typically work on pattern models. Because the wing loading is so low on a pattern model, it becomes unstalled if you unload the elevtaor and stopps snapping. Just wanted to add that.
