I respectfully disagree with the rudder on the left stick approach. When a plane has a lot of dihedral and no ailerons, the rudder control is really creating roll as much as yaw, and for many purposes, affects the plane like ailerons do. A beginner at our club who was urged to do this by someone at our field just got frustrated with it.

I flew with rudder, elevator and throttle for years before my first aileron plane. I always used rudder on the right stick. Yes, I had to learn to use rudder in a different way when I switched, but that is inevitable.

However, I did use a computer radio to put the rudder on both sticks so I could learn take-offs with the left stick. Then the transition to ailerons was effortless.

For a glider, of course, you don't have to worry about that.
