The world's smallest helicopter will soon be taken to flying in honour of Leonarda Da Vinci, who, in the 1480's, had designed some sort of helicopter on his papers.

75-year-old Japanese Gennai Yanagisawa is planning to demonstrate his copter on May 25th in Leonardo's birth place Vinci, Italy.

Italy's museum of science and technology holds that the "aerial screw" drawn by Leonardo had been the world's first scheme of a helicopter.

The world records filing publishing house of Guinness confirmed in any case, that the 75 kilogram weighing copter is the world's smallest. Its rotors diameter is four meter. Yanagisawa already sold six of his GEN-H-4-copters and hopes, that "one day people will use them like scooters."
