The GT60 is the latest gasoline engine from O.S., and it gives fliers of popular 50cc class aircraft everything they want most - durability, efficiency, easy operation and super-strong performance. Instant throttle response makes the GT60 an outstanding choice for 3D flying. When pilots need more power ASAP, this engine delivers! Modelers asked for a conventional, rear-mounted carb and rear valve, and O.S. listened. The carburetor is custom-designed specifically for this engine by Walbro. O.S. also takes advantage of liner-less cylinder construction for the GT60, and machined the head and cylinder as one piece rather than joining them with bolts. Benefits of the overall cylinder design include lower weight, improved cooling, and exceptionally efficient exhaust scavenging.

The GT60 gasoline engine is available with or without a Pitts-style E-6020 muffler. The muffler includes anti-crush tubes for the mounting bolts and webbing reinforcement at high-stress points, for a long life of performance-enhancing operation.

- Rear-mounted carburetor, provides several performance benefits
- Better head cooling, for more consistent engine runs and high performance
- Requires shorter standoffs, which results in more secure installation (mounting) and less vibration overall
- Very simple, direct installation of the throttle and choke linkages
- The GT60's liner-less cylinder head lowers weight, improves cooling, and contributes to increased efficiency
- Unique 1-piece crankcase design eliminates gaskets and enhances strength and precision
