I think my teacher set the rudder up on right stick to make it easier for me to progress to ailerons, at that time in the 70's there were no transmitters with mixing channels or expo at least that I could afford, I'm just fine with the rudder while on the ground and in the air, problem is training my elevator thumb to not command the ailerons in a turn if I don't want it to, it's a natural impulse now.
