Spotlight: O.S. Engine GT60 Gasoline Engine

The O.S. GT60 gives fliers of 50 cc models everything they want in a gasoline engine — durability, efficiency, easy operation and super-strong performance. The GT60's liner-less cylinder construction lowers weight, improves cooling and increases exhaust scavenging efficiency. Intake and exhaust timing are perfected as well. Instant throttle response makes this an outstanding choice for 3D flying. When you need more power ASAP, the GT60 delivers!
