Quote from Dan Winterland:
The recovery actions are simple. Centralise the controls and close the throttle. If that doesn't work, you are probably in a fully developed spin and should use your type's recovery technique.
From my experience in spin training in relatively violent spinning GA aircraft, could you not possibly accelerate the spin at the midpoint of the incipient stage with the centralizing of the stick position (i.e. from the spin generating input) without first an anti-spin rudder application? While if this does happen, your statement should still get you out, it will have put the aircraft in a worse spin mode and further delay the recovery.
Mind you I have yet to try this general procedure in my normal aircraft, I will at my next opportunity. In my experience with this plane (Morovan Zlin 242L), it is very willing to accelerate with opposite pitch input and centralized rudder. In-fact some acceleration, while minor, can be noticed during the manufacturer prescribed recovery technique, when the stick is brought forward (erect spin), after full opposite rudder has been applied on its way to unstalling and recovering.
