Rob, et.al.:

Apologies in advance for a noob question.

I have read how your rudder system has evolved. I think you have it well sorted now, but i did wonder, have you ever experimented with rudders that change direction in a shunt via being raised and rotated 180 deg around the 'kick up' axis?

I have read that t speer designed a double symmetrical foil that works well, (NACA0012 like) and that seems a simpler rudder system.

I was wondering if asymmetric foils that flip might be less wetted area and higher lift or lift/drag. Perhaps a racer option?
