Product Details



Everyone knows about how the FS56-a, FS81-a and FS110-a deliver superior 4-stroke power and performance, as well as how they've revolutionized the engine industry. Now, O.S. has filled in the missing link with the release of the FS72-a. Pilots of .60-sized aircraft can now enjoy such FS-a benefits as a blow-by internal oil system. It eliminates the need for a crankcase and re-circulates excess oil throughout the engine. No fuss...No muss...Just a first-rate engine that sets new standards while continuing traditional O.S. quality. The FS72-a Four-Stroke – only from O.S.
The adjustable F-5030 muffler can be rotated 360° and moved in or out for a perfect fit. Rich, deep sound is an added benefit.
A reversible carb and narrower camshaft housing simplify installation.
Tighter tolerances and updated engineering reduce maintenance and ease set-up.
Delivers more performance power to sport pilots and more realistic flight to scale pilots.
