Zenoah G-50 Explained

The Zenoah G-50 is a twin-cylinder, horizontally opposed, two stroke, carburetted aircraft engine, designed for use on ultralight aircraft.[1] [2]

Development

The Zenoah G-50 is equipped with single capacitor discharge ignition and dual Mikuni slide-type carburetors. It is equipped with a recoil starter system or optionally electric start and a 2.1 or 2.6:1 belt reduction drive.[3]

The engine runs on a mixture of unleaded auto fuel and oil.

Producing 450NaN0 at 5800 rpm, the G-50 competed in the early 1980s ultralight powerplant market against the similar Rotax 447. Production of the engine was completed in the late 1980s and today only used engines and parts are available.
