O.S. Engine OSMG0980 FS-200S Surpass Four-Stroke Performance Engine  [OSMG0980]

Power and packaging from the O.S. FS-200S Surpass

The O.S. Engine FS-200S Surpass, model OSMG0980, demonstrates how a compact four-stroke can raise performance expectations. It fits in similar mounts to the FS-120S-P while supplying a clear step up in usable power for pilots who want both punch and scale authenticity.

Balanced output for sport and scale use

With a displacement of 1.98 cubic inches (32.4 cc), the FS-200S offers a strong mix of power and fuel economy. Rated at 3.0 horsepower at 9,000 RPM, its practical RPM window from 1,800 to 10,000 gives you flexibility for relaxed cruising or more aggressive aerobatic work.

Installation-minded design

The F-6010 muffler can rotate a full 360 degrees and adjust in and out to suit tight cowlings, helping installers get the exhaust orientation they need. The reversible carburetor and the narrower camshaft housing also simplify fitting into a variety of airframes.

Fueling and power improvements

The FS-200S-P version adds the PD-08 fuel pump to keep fuel supply steady through unusual attitudes, while both variants feature a larger carb intake and port that deliver almost 43% more output than the FS-120S-P. These refinements translate to stronger midrange and top-end performance.

Whether you fly sport models or scale ships, the FS-200S Surpass brings real four-stroke characteristics and easier installation choices that appeal to builders and tuners alike.
