Trying To Spin Off A Slip
DISCLAIMER - I am not a CFI and this is not a tutorial. It is an observation of one specific set of circumstances.
WARNING - may not apply too your aircraft type / configuration.
SUGGEST you do not attempt to explore this part of the performance envelope unless you have received spin and upset recovery training. And if you do it is AT YOUR OWN RISK.

After a discussion with a fellow pilot about the risk of spinning off a slip - I went out to verify (at a safety altitude of 5-7,000ft AGL) that this Cessna 150 would tend to bob and tuck rather than spin if stalled off a fully developed and stabilized slip.
In fact the plane never really stalls with a break. And it is not spinning. It is rotating about a vertical axis from wingtip to wingtip. But it has a Vertical Airspeed in excess of 2,000fpm downhill. So not a good idea in the traffic pattern!
Recovery was with normal - stall recovery (pitch down - then roll level) rather than spin recovery control inputs (PARE).
The plane is NOT in a spiral. Airspeed remains pegged on the bottom of the arc at almost nothing throughout.
