Stall turn:
Throttle back and full rudder for the airplane in YouTube's film.
In AH?
I suspect that it works so.
Nose up; bank (to the right for example) and push forward a bit on joystick (just to maintain the initial flight plane path);
stop banking, full opposite rudder (left rudder)
and simultaneously push forward a bit on joystick (just to maintain the initial flight plane path).
Agree?
