Spinning, my favourite subject!
Only last week I was out in a C150 with a photographer circling at 1000 ft with various combinations of bank and sideslip (flaps up) thinking that an unwary pilot could get a shock doing things like that.
I get to spend some time in Aerobats showing budding instructors the spin, including some inadvertent entries and they are invariably impressed with how quickly it can autorotate from a stall in a turn, given the right control actions from myself.
For more info on spinning Cessnas - here's a copy of a Flight article from 1978:
