GT15 15cc Gas 2-Cycle Airplane Engine with Muffler (OSMG1515)

GT15 15cc Gasoline 2-Cycle Engine with Muffler is OS Engines’ compact gas-powered powerplant for RC airplanes. It delivers the performance of a .90 four-stroke or .60 two-stroke glow engine with the fuel economy of gasoline, while remaining light enough for airframes that require a 61-size two-stroke or 91-size four-stroke installation. Weighing about 904 g and capable of over 2 horsepower at up to 15,000 rpm, it fits a broad range of models. The package includes a purpose-built OS carburetor, the IG-06 ignition module, and a Power Box muffler to simplify setup and operation.

Designed for easy tuning and crisp throttle response, the GT15 uses a specially designed OS carburetor with a regulator and pump for reliable fuel delivery. A roller bearing on the large end of the connecting rod enables a 50:1 fuel/oil mix, and the engine shares the same mounting pattern as the 65AX, easing installation in established airframes. The included ignition module and muffler help ensure reliable starts and efficient, quiet running at speed.
