During spin recovery, can you just release the yoke/stick to neutralize the ailerons? I have been watching spin recovery videos on YouTube for the last few days. Scary stuff and I haven't even started flying yet :o haha 

Anyway, the recovery seems to be commonly described as PARE: 


Power idle
Ailerons neutral
Rudder opposite of spin
Elevator forward


Do you physically neutralize the ailerons or does releasing the yoke/stick do that? Is that specific to certain airplanes?
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.
