I had a similar learning experience as the original poster. I was practicing power off stalls with my instructor early on in my PPL training. I set the a/c up for the procedure, and for some reason or another (can't remember) the aircraft began a slight roll to the left just prior to the stall. I was a moron, and inputed quite a bit of right aileron to correct, right as the aircraft was stalling. This obviously stalled one wing more than the other, and scared the living piss out of me. It was in a 172, which we all know is a very difficult aircraft to spin, but my instructor told me that without realizing it I initiated a textbook spin entry. Had it been a different a/c, it probably could have been a full on spin. If I was soloing, that would have been a bad day. I would definitely like some hands on spin training. I think I'll wait for uncle sam to fit the bill for it though.
