During spin recovery, what should the pilot do with rudder controls?

During spin recovery, applying full opposite rudder is essential because it helps counteract the yawing motion caused by the spin. As the aircraft enters a spin, it rotates around its vertical axis due to an imbalance in aerodynamic forces. The use of full opposite rudder effectively counters this yawing motion, aligning the aircraft with the relative wind.

This action works in conjunction with other recovery steps, such as reducing power and initiating a controlled forward pitch to break the angle of attack. The full opposite rudder serves to push the nose of the aircraft in the opposite direction of the spin, thereby reducing the rotational speed and allowing the wings to regain lift, which aids in recovery from the spin.

Other answers suggest varying levels of rudder use or even recommend not using the rudder at all, which would fail to address the critical yaw component that needs to be corrected for effective spin recovery.
