ADEYTO meets 75-year-old Gennai Yanagisawa, who runs an electronics equipment company in Matsumoto, central Japan, has created a 75kg (165-pound) one-man aircraft which sets the world record for the smallest helicopter.




Gen Corporation, the company employee Yasutoshi Yokoyama flies in the air by GEN H-4, a compact single-seater helicopter developed by Gen Corporation, during its test flight in Matsumoto in central Japan's Nagano Prefecture. Yanagisawa developed the GEN H-4 helicopter — with rotors, a chair, footrest and handle bar — in the late 1990s.

Yanagisawa's helicopter is the smallest model in the world in terms of weight and its rotor length of 3.9 metres. The GEN H-4 has two rotors turning in opposite directions to maintain stability, and four engines that enables a 30-minute flight with a top speed of about 56 miles per hour.

The helicopter has two identical rotors that turn in opposite directions making the need for a tail rotor obsolete. Each rotor counteracts the others torque keeping the helicopter free of any unwanted spin.




Controlling the GEN H-4 is very easy.If you wanted to go forward, you would pull the control bar toward you. If you want to go to the right, you would move it to left, and want to go left, move it to right. Of course you can reverse the helicopter. you only have to push it forward. The rise and descent are controlled by the throttle. If you push the throttle lever, GEN H-4 goes up, you let it, GEN H-4 goes down. If you wanted to turn to the right or left, you would push yaw-control-switch by right hand.

The entire rotor head is supported on a gimbal, which is slanted towards the direction of travel by the control bar. The pilot can therefore change their direction by shifting their weight.

It has four twin cylinder engines and can remain in the air even if two of the engines of malfunction. However, they have attached a parachute above the mast just in case....

Da Vinci designed what is thought to be the first vertical flight machine, "an aerial screw," in the 1480s, according to Italy's National Museum of Science and Technology.

Yanagisawa, who was named after Hiraga Gennai, an inventor during the Edo period (1603-1867), by his father, became hooked on making helicopters after turning 50.

The first prototype he created in 1995 hovered several centimeters above the ground for just a few seconds, but after poring over books and other materials, including some 50 years old, he managed to solve the technical problems that had been hindering his flight. Yanagisawa's initial motivation for his creation was to develop an unmanned helicopter for spraying pesticide. Yanagisawa has sold five GEN H-4s in Japan and two in the U.S. for recreational use. The helicopters sell for about $57,140.

  • @EnigmaV8 The name of the song is "multiplying by seven" and the author is Kidzup. Normally, there are lyrics, but I think that with the name, you should find the without lyrics version quite easily.
