The Cessna 150 will do an inverted spin, if you know how to mishandle it right.....
Spins have always been seen as a 'big scary moment'. I don't particularly remember my first spin. But then that was probably ignorance on my part. I tended to regard it as just another manouevre albeit interesting. It hadn't been built up in my mind as a big deal. But then I like aerobatics, not all pilots do.
Since then I had a quite a few spins. They are dangerous if you start the spin too low. That killed someone I know not too long ago. I think it's a good idea that they were taken out of the syllabus for the reasons described. But I also think that an Instructor should demonstrate one if the student is willing. If only to emphasise what will happen if the really do mishandle the aircraft.
