O.S. GT60 Aircraft Engine

GT60 Gasoline

MORE POWER for 50 cc class aircraft

The GT60 is everything 50 cc fliers want in a gasoline engine — durable, efficient, easy to operate and high performance. A liner-less cylinder makes the engine light, makes it cool faster and gives better exhaust-scavenging characteristics. Plus, its throttle times make the GT60 the choice for 3D flying, delivering power when you need it.
