World’s Smallest Helicopter: The Guinness World Record Holder


Guinness World Record holder for the smallest helicopter is the GEN H-4 developed by the Japanese engineer Gennai Yanagisawa. The GEN H-4 weighs only 155 lbs with a height of 5.1 ft and a rotor length of 18 ft. This helicopter can fly at a speed of up to 50 mph and has a maximum altitude of 2,600 ft. The GEN H-4 is a single-seater aircraft and is best suited for short-distance flights, as it runs on gasoline and has a flight range of just 30 minutes.

The GEN H-4’s Development Process

The GEN H-4 was designed and developed over a period of 25 years by Japanese engineer Gennai Yanagisawa, who started his work on the helicopter in 1971. After numerous trial and errors, Yanagisawa was finally able to complete the model in 1994. The helicopter’s unique design consists of two rotors that rotate in opposite directions, and the pilot-controlled the aircraft’s movement using a joystick attached to the main rotor. Yanagisawa’s vision was to develop a compact, affordable, and easy-to-operate helicopter for personal use, and his dream came true with the GEN H-4.

The Current State of the GEN H-4

Although the GEN H-4 was developed in 1994, it still holds the Guinness World Record for the smallest operational helicopter. The helicopter gained popularity worldwide and has been featured in several TV shows, news articles, and documentaries. Yanagisawa’s company, Yanagisawa Technology, still sells the GEN H-4, with the current model known as the Yanagisawa GYROPLANES. The company has made several modifications to the original model, improving its performance, safety, and flight duration. The Yanagisawa GYROPLANES are not only used for personal use but also for commercial purposes like surveying, photography, and law enforcement.
