Unless the aircraft is in a fully developed spin use of rudder will probably just make things a lot worse. Ref the Avweb video with the Cirrus going into a snap roll at about 200 feet AGL because someone did exactly this, it is a vid I show students before the stalling lesson.

Plus a proper analysis rather than old wives tales here https://www.richstowell.com/document...a_TP13748E.pdf

"One feature that stands out in all except one of the 39 stall/spin accidents examined is that knowing how to recover from the stall or spin was of no benefit to the pilots in these circumstances. They stalled at altitudes so low that once the stall developed, a serious accident was in progress"

This is what students need to study, not have instructors yank and shove little aeroplanes around at 3500 feet.
If you continue teaching people to ignore appropriate rudder use in the incipient spin scenario then they will nearly always revert to picking up a dropped wing with aileron (law of primacy) which will actually work in many modern aircraft, but will produce the below result in others - note aileron & rudder deflections. Is it a good idea to teach for the best-case scenario or the worst?
