Dragonfly DF1
Designed and built by the now-defunct Swisscopter AG, the Dragonfly DF1 is a one-man helicopter that uses a pair of hydrogen peroxide fueled rockets attached to the tips of the rotors for power instead of a more conventional gas turbine engine. Weighing just 234-pounds, this helicopter can still carry a 500-pound load – pilot, fuel and cargo. The rockets enable it to achieve a top speed of 115mph and cruise at 40mph for up to 100-minutes with an extra fuel tank.



You don’t control the Dragonfly DF1 like any other ‘normal’ helicopter either. How so? Rather than a joystick for banking left / right and controlling forward / backward movement, there’s a single collective control for engine power, as well as a set of rudder pedals for yaw control. Plus, the Dragonfly DF1 gets a much simpler handlebar mechanism which hangs down from the rotor head and allows the pilot to control the angle of the blades, while a throttle lever allows for power adjustment.
