FSa-72II Airplane Engine with F-5030 Silencer (OSMG0878)

OS FSa-72II Aircraft Engine with F-5030 Silencer is a four-stroke powerplant designed for sport and scale RC airplanes. It delivers strong, steady performance and a deep, authentic sound, helping sport flyers push their models and scale pilots enjoy a more realistic flight experience.

The F-5030 muffler can be rotated a full 360 degrees and moved in or out to achieve a precise fit in your airframe. It shares the same mounting bolt pattern as the FL-70 and FS-70 Ultimate for easy replacement. A reversible carburetor and a narrower camshaft housing simplify installation, while tighter tolerances and updated engineering reduce maintenance and speed setup. In practice, this engine provides enhanced power for sport flying and a more lifelike feel for scale models, complemented by a rich, deep exhaust note.
