I 've done scores of intentional spins in gliders so am happy with them. But I was surprised how quickly the C150 flicked over into a spin - we were at 4000 over the sea at the time and when it ran out of flying speed, the upper wing lost life and dropped us into a spin. Others who know more about aerobatics than me can comment more.

Spinning is no longer in the syllabus - it was when I converted my licence to a UK one. But the method of getting into a spin then was the unreal one of stalling and then kicking in rudder. Then you expect to spin.
But flicking into a spin out of a turn is a powerful lesson.
