The GC-201 from Geocopter allows the US military to use unmanned helicopters for stealth missions. Designed and built like a normal helicopter, the GC-201 features a twin gas turbine engine propulsion system, lightweight carbon fiber fuselage and full automatic takeoff, mission, and landing capabilities.
It can cruise at 46MPH and can fly as high as 6,500 feet. The GC-201 carries a 66 pound sensor payload that brings its original weight to nearly 200 pounds. With the sensor payload attached, the helicopter can remain in flight only for about three hours, perfect for short missions.
