Couldn't resist adding my 2p worth!
With respect to spinning , I once did an aerobatics course at Purdue University. Part of the course included what the instructor called "the big spin".
Climb (eventually) to 9000', enter spin and then try various effects of controls - in and out spin aileron, slightly forward stick, full power(!) to observe the effect, and recover. A total of 11 turns! The recovery took about one and a half turns.
