The 75-kilogram helicopter will make a demonstration flight in the city of Vinci, near Florence, on May 25, according to Japanese developer Gennai Yanagisawa, 75.

"Since the concept of our helicopter came from Italy, I always wanted to take a flight in the birthplace of da Vinci," Yanagisawa said.

"I feel like I'm greeting an ancestor. I hope da Vinci would be pleased," Yanagisawa said.

Yanagisawa said he went to Vinci in February and received the blessing of Mayor Dario Parrini. The helicopter, named GEN H-4, has a set of two rotors turning in opposite directions and can fly at a maximum speed of 50 kilometres per hour.

Guinness World Records in February recognised it as the world's smallest helicopter that can carry a person.

Renaissance genius da Vinci was born in Vinci in 1452 and spent the first several years of his life there. His sketch, dated in 1493 and discovered in the 19th century, shows a vertical flight machine. As in the drawing, the GEN H-4 has no tail.
