I learned in flight school that the rudder is used counter spin wise to stop the turning.
My tests in CoD confirmed that for me.

For the ailerons, in a spin there is no airflow over them because the plane is stalled.

Usually the rudder is the only working control in a spin, the elevators really start working when the spin is stopped and last the ailerons start to function when the plane is out of the stall
