Gen H-4 Personal Helicopter
Gennai Yanagisawa, inventor of the GEN H-4 personal helicopter, will be taking flight in Italy in order to pay homage to the birthplace of da Vinci - the man who came up with the helicopter view a few hundred years ago. Yanagisawa’s GEN-H4 design chases the original “ornithopter” design by doing away with the tail, using twin counter-rotating propellers that cancel out the torque generated by single-rotor helicopters, requiring those to have a perpendicular tail rotor instead.
