In training my instructor setup an approach situation with 1500rpm 30% flaps and told me to hold the aircraft level with the airspeed bleeding off. He did not tell me what would happen. It suddenly dropped the right wing, I dropped the nose and pushed with the left foot. Ended in a anti clock spin with flap & 1500rpm. By the time I had raised flaps throttle closed & sorted it out, we lost 1500ft. Or 1000ft under ground as classic stall spin turning on to approach, next try only lost 300ft. I believe this is better training than the classic clean stall spin training, real world setup and hard lesson.
DON'T DO THIS UNDER 4000FT AT LEAST.
