I built the RC Hovercraft from jscaylor. It's really fun to drive the hovercraft. But I always had problems steering right. There, the rudder effect was not enough to be able to drive around the corner properly. With the new rudder blade in the middle now both ways are the same and the hovercraft drives now clean around the bend.

Only one part is needed at a time. The rudder is modular and therefore suitable for both directions. ( cw or ccw )

I just tried to film that, but both are not really working at the same time. But I think you can still see the maneuverability well.
