Nicholas Rehm, inventor of the dRehmFlite stabilization system, built this 50 lb, 12 ft diameter, powered rotor helicopter controlled with his stabilization system. It had never been flown before and this is it's first flight, during one of the combat events. The cyclic control was not properly tuned and the copter drifted with the wind until he had to land at the edge of the field, but it was very impressive in the air and nothing looked like it could stop it!
