The Tradition Continues...
Everyone knows about how the 56FS-a, 81FS-a and 110FS-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 72FS-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 72FS-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.
