Well Angels, I was giving you the benefit of the doubt, but now I know you're full of it. The Astar IP is by no means the center stack variety:

Back to the original topic, Keith, I did a little more searching of the ol' memory banks, and managed to dig out the connection between rotary engines and left hand traffic patterns. Specifically, it was the fact that for airplanes with a clockwise rotation of the prop (and hence engine), a right yaw would induce a downward pitching motion due to gyroscopic effects. So right turns, especially after takeoff, could get a new pilot into serious trouble if he wasn't prepared.
