OS 120AX Ringed 1.20 Glow Engine with Muffler is a high-performance powerplant for sport and precision RC airplanes. With roughly 25% more displacement than a .91, it lets you swin g larger props while keeping the same mounting footprint and only a light weight increase. The Power Box muffler is included to expand mounting versatility, and two adapters are supplied—one can rotate the muffler 90 degrees for a Pitts-style layout—so it fits a wide range of airframes without aftermarket modifications. Ideal for 3D, precision aerobatics and sport flying, this engine features a ringed head design and an angled heat-sink head that adds cooling surface area for reliable performance. It installs into airframes sized for a 1.20 glow engine, delivering strong thrust with a straightforward setup and flexible exhaust orientation to suit the airframe’s layout. Show more
