Doug,

Your main problem will be finding an airfoil where the upper curvature matches the wing saddle ... that being said, the SD 6060 ought to be fairly close, and is a darn good all-around airfoil. I would suggest laying it out so that you have a span of 45 inches or so, a tip chord of 5 to 6 inches, and 1/2 to 1 degree of washout at the tip.

I remember Bill Weesner. He was basically unbeatable until the day he decided to do a quick paint job in his basement without a mask ... DuPont Imron catalyzed urethane. I don't think he ever flew again. Beware.
