(P.S. Hey I skydive near you out at Rick's in Petersburg.)

cold air is dense air and gives much more lift than warm air at least that's what the full size

pilots tell me.

BillyD... you have verified that the KFm4 is a very fast airfoil. This is what RCPowers noticed when testing the four variations. I would also love to see how slowly yours can fly. Hopefully it will have a very wide speed envelope. You've made a nice looking aircraft. The shape is very pleasing to the eye.
