Rudder on the left is normal but I understand what you are going through. I just built a little 3ch plane and decided to keep the rudder on the left stick, I kept forgetting it was there and I kept trying to set up my turns with my right stick and the plane wasn't doing anything until I remembered it was rudder controled on the left stick. I was really having problems. When I got home I set the plane up with rudder and elevator on the right stick and the world became an easier place to live. I just couldn't get used to making a turn with rudder only on the left and kept looking for my ailerons. You will get used to having a normal 4ch plane with a little time. Ailerons are your friend!!!
