Imagine one of Leonardo Da Vinci's designs from 1493 coming to life more than 500 years later!!! Talk about imagination. If you think about it's amazing that Da Vinci's 500 years ago designed a machine that would allow a man to fly through the sky like a bird...
The GEN H-4 Co-Axial, Counter Rotating helicopter is the worlds smallest one man helicopter and was designed by a 75 year old Japanese gentleman named Gennai Yanagisawa.
Mr. Yanagisawa's design was officially entered into the Guinness Book of World Records for a 75kgs helicopter that can carry a single person.
Genni Yanagisawa's design uses a two rotors spinning in opposite directions and can cruise at over 30 miles per hour.
One Big advantage to the single person helicopter versus a jet pack is the amount of time it can stay up in the air. A jet pack can only stay up for a few minutes, where the helicopter is much more efficient and can stay up much longer.
