Ok, I know it is bad, but we "brother of the foamie" out here in Iowa are actually trying to organize an air battle, but FULL CONTACT, and with Foamie style planes. You can modify your plane anyway you want, metal prop, whatever.

10 minute rounds, TKO is in affect as you can try to land on the landing site to make repairs, but open to attack when trying. Only rule, can't attact another pilot or touch them in any way. The Combat is in the air, and only the air. Last plane flying, or last to hit the ground wins.
