One-Man Helicopter

If it ever gets launched commercially, it would transform the way we commute.  Not considering the traffic problems in heavily populated cities.

The GEN H-4 can fly to a maximum altitude of 1000 meters at a top speed of 90 km/hr (59 mph) for up to 30 minutes

If flying is your thing, check out the GEN H-4. Powered by 4 x 125cc 2-cylinder engines, the H-4 boasts "2 sets of coaxial, contra-rotating rotors, which eliminates the need for a tail rotor." Two caveats: you have to build it yourself and it costs $30,000. Product page here. See it in action after the jump.

It's the "GEN H-4." The world's smallest co-axial helicopter ever made! (that actually flies)

This is a Japanese designed and manufactured ultralight one-man helicopter. The total empty weight of this helicopter is only 155 lbs.

Yes, you're right it is a quite interesting contraption! It is true that there is not much to see on the outside. The frame is 2 inch aluminum pipe bent and welded, with a fiberglass backpack and funny looking wheels. The controls are direct, like many gyrocopters. In front of the pilot attached to the control bar is the control panel with the throttle (altitude control), tachometer, ignition power, starter and yaw switches. The tools necessary for flight do not seem like much because they aren't. This is not only the lightest helicopter in the world, but it is the easiest to fly!

If you look closely at the power pack (on top of the air craft) you will find four astonishingly small twin cylinder engines feeding into a central transmission with two sets of rotors turning in opposite directions. Wow, you say? That's nuts! Well, if you're still interested and would like to see one fly please follow the links below and at the top of the page to learn more about this amazing helicopter.
