Recognized as the world's smallest co-axial helicopter in the Guinness Book of Records, the GEN H-4 is a one-manned helicopter that can make one's childhood dream of flying openly in the sky come true.

We provide global sales and marketing support for the GEN H-4 in addition to flight training and technical services to our distributors and end-users. Whether for personal enjoyment or business use, we can customize your H-4 to stand out from the crowd or provide solutions across various industries that could help you improve productivity in your business using the H-4.

The GEN H-4 is powered by four GEN 125 engines (125cc, two-stroke boxer twin, 10 hp per engine) with a total output of 40 horsepowers. Each engine has its own independent ignitions, carburetors, starters, and centrifugal clutches and operates at 7,250 to 8,400 rpm, while the rotors are counter-rotating that typically operate at 800 to 900 rpm.

Running on unleaded automobile gasoline, the GEN H-4 is safe, stable and easy to fly. Similar to how one would ride a motorcycle, simply strap-on the safety belt, start the four engines and take off into the sky. Take off vertically, and fly to your heart's content.

Due to the compact, ultralight nature of the GEN H-4, it can be stored in less than half the space of a family-sized car after partially dismantling the unit. Weighing only 70 kg (155 lb) it could be easily handled by one person. Carry one on-board your truck or boat to your location of choice, and take off into the sky in minutes.

The compact size, versatility, and low operating costs all make the GEN H-4 ideal for a wide variety of recreational, commercial, and industrial use. Possible applications include Surveying, Surveillance Patrol, Rescue, Firefighting, and Agriculture.

Fly to places where no conventional aircraft could land or take off.
