Guinness World Records 2013

Smallest Helicopter

In terms of rotor length, the smallest helicopter is the GEN H-4 made by Gen Corporation (Japan) with a rotor length of only 4 m (13 ft), a weight of only 70 kg (154.32 lbs), and consisting of one seat, one landing gear and one power unit. Unlike more traditional helicopters, it has two sets of coaxial contra-rotating rotors which eliminate the need for a tail rotor for balancing.
