I don't wish to instigate thread creep - this discussion has stayed within the realm of powered aircraft, and for the most part what has been said in so many different ways obviously remains valid for that broad branch of aviation. However in the world of glider flying it appears to be different. The idea of "grabbing" a dropping wing at the stall with opposite rudder - not aileron - was drummed into me some 54 years ago as a student in that discipline, and I vividly remember what took place in the practical demonstrations which were part of the experience.
I'm well out of it now, and gliders have changed enormously since those days, but from what I read, it's still applicable in the general sense for gliding. Certainly, this quote from the current Gliding federation of Australia manual suggests that: "Most gliders still have some aileron authority at the stall but don’t use ailerons because that itself may cause the glider to enter a spin". (Australian Gliding Knowledge, page 67)
