Here is a photo of the above mentioned plane. It has an MH30 airfoil. I'm really pleased with its flight performance. It does about 80 mph and loses very little speed in the corners.

Ollie,
Would you agree that shortening the span decreases frontal area and should increase top speed? Similar to what they do to full scale unlimited pylon racers, like Strega and Rare Bear. They cut several feet off each wing tip, the planes are lighter without guns, ammo and armor plating which means they need less wing area. The side benefit from that is increased speed. Or do they do it just for a speed increace reguardless of wing loading.
