The World's smallest one person helicopter
the GEN H-4 from Gene corporation - Japan is your personal helicopter. It comes with a seat and landing gear so all you have to do is strap on and you are ready to go. Unlike traditional helicopters it has 2 sets of coaxial, contra-rotating rotors (KA-52 Hokum) which eliminates the need of a tail rotor for balancing. The rotors have a length of only 4 meters so no parking problems too. It is powered by 4 lightweight 125 cc 2 cylinder engines which use standard gasoline. The GEN H-4 can fly to a maximum altitude of 1000 meters at a top speed of 90 km/hr (59 mph) for upto 30 minutes. You dont require a license to fly the GEN H-4 in Japan and the inventors claim it is easy as riding a bicycle and with just 2 hours of practice you can master it. The controls also resemble a bicycle handle.
Gene corp is selling it as assembly kits. It is available in Japan for 3,780,000 Yen ($ 32,500).
