Don't tell the fuzz please -
I once went out for an hour or so in a PT-22 with Irwin Treager (of Aircraft Gas Turbine Engine Technology fame) in the back seat. We had seat chutes in the bucket seats, but they weren't legal (slightly out of date) so we weren't planning aerobatics - just normal PPL lazy eights, slow flight, stalls ...
After a few normal power-off stalls, he suggested I try one cross-controlled. I held about one-third rudder with opposite stick as we approached the stall -
Then ZOOM! The horizon turned 360° before I had a chance to even think about recovering! The PT-22 was notorious for approach-configuration stall-spin accidents, and I just had a demonstration (at 3000' fortunately).
The little Ryan had just a few degrees sweepback, and I quickly learned what sweepback means in yawed flight.
