As far as I know, the rudders are not designed to change course of the aircraft. As I understand there are only two usecases for the rudders. First to adjust the noseheading on final approach in the case of crosswinds to hold the glidepath and second you can use the rudders on high angles of attac and low speed to roll the aircraft, because aileron inputs cause the opposite reaction than intended under these conditions. And of course you can use the rudders to make smoother turns while banking like you would do on a light prop plane but honestly I didn´t noticed any positiv effect on my turns, so I just keep my feet off the pedals during the normal flight.
