GEN Corporation of Japan developed a personal helicopter named the GEN H-4, but production was deferred pending large enough orders to make the aircraft economical.[1][2]
The company also developed the GEN 125, a very small 8 hp (6 kW), twin-cylinder, two-strokeaircraft engine to power the H-4. The engine weighs 3 kg (6.6 lb) and four are used in the H-4 design to provide redundancy.[1]
The company does not have any fixed location, but has carried out its development work in borrowed facilities.[3]
The company name translates as "fountain of wisdom".[3]
