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 idea a few hundred years ago. Yanagisawa’s GEN-H4 design follows 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. The GEN H-4 personal helicopter isn’t doing too hot in sales though, considering its sky high price of $58,250. So far only half a dozen units have been sold worldwide, but at least you get a birds’ eye view on the way to the office at 31 mph.
