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

Compact power from the FS-200S Surpass

The O.S. Engine FS-200S Surpass, model number OSMG0980, packs increased output into a footprint similar to the FS-120S-P. That makes it a practical upgrade for models where space is tight but extra power is wanted.

Strong midrange and flexible revs

Displacing 1.98 cubic inches (32.4 cc), the FS-200S produces 3.0 horsepower at 9,000 RPM and performs across a 1,800 to 10,000 RPM band. That range delivers usable thrust for both scale cruising and aerobatic routines.

Practical fitment features

The rotatable F-6010 muffler and reversible carburetor help resolve cowl and throttle linkage challenges. The narrower camshaft housing also eases installation into slimmer noses or tighter engine bays.

Improved fuel system and output gains

The FS-200S-P's PD-08 pump keeps fuel flowing through steep climbs and unusual attitudes. Along with a larger carb and intake port, the design yields roughly 43% more power than the FS-120S-P in similar installations.

For model builders seeking a compact engine with authentic four-stroke feel and extra grunt, the FS-200S Surpass is a practical and capable option.
