Message: I've noticed alot of people using the term "snap roll" to describe either a maximum deflection aileron roll, or a full deflection aileron and rudder roll.

I'm pretty sure this is incorrect. A snap roll (to the best of my knowledge) occurs when the pilot pulls the stick hard enough at a moderate speed to force one wing past its critical AOA. This destroys all lift on the stalled wing, making the plane pivot VERY rapidly (more rapidly than you could possibly do it with your average WW2 ailerons) around the stalled wing. Opposite rudder is used to stop the roll. Try it in a 190, which I've found the maneuver to work best in. The 190 has a great roll to start with, but particularly if you're too low and slow to extend (or you have a faster plane behind you) the snap roll can be used to dance around until they overshoot, or lose enough e for you to point the nose down and head for the hills.

Just my $.02. If anyone knows more than I do, I please post it.

Exactly which way do you pull the stick, referenced to say, stalling the starboard wing (or port, whichever you prefer)? Also, does torque effect this maneuver? Thanks for a cool contribution!

Back hard and suddenly. And rudder away from the predominate stall wing. So in a 38 left.
