| 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.

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.
