The Sikorsky RAH-66 Comanche was one of the most ambitious helicopters of all time. It was a stealth armed reconnaissance and attack helicopter designed for the United States Army. The Comanche was recorded as having attained a cruise speed of 162 knots (186 mph; 300 km/h), as well as having achieved a "dash speed" of 172 knots (198 mph; 319 km/h). It could even perform a 180° turn in under five seconds! This remote controlled helicopter is much smaller than the full sized original, but it is still fun to fly. Officially licensed from Sikorsky!
