During spin recovery, can you just release the yoke/stick to neutralize the ailerons?
You do not want to put aileron inputs during a stalled condition, as this can induce and/or further aggravate a spin.  So a neutral control position should be assumed with the stick prior neutralizing the spin with opposite rudder input.

Spin recovery techniques vary a little between manufacturers and specific aircraft but the PARE method (Beggs/Muller technique) is one of the most common recovery methods out there.  Alsways use the approved spin recovery technique listed in your airplane’s AFM.
