It is not quite that simple. I learned on Gliders, so right hand on stick, left on airbrake. If I am flying a single seat I always fly right handed. However in a DR400 there is a throttle on the left, but nothing else. To fly a go around from 200ft you open the throttle with your left hand, swap hands, and push the carb heat in with your right hand, not good! In this case I fly left handed.
