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

Overview of the FS-200S Surpass four-stroke

The O.S. Engine FS-200S Surpass, model OSMG0980, delivers a clear increase in power while remaining compact enough to fit where the FS-120S-P was used. It appeals to flyers who want authentic four-stroke operation and stronger performance in a neat package.

Engine performance at a glance

Featuring a displacement of 1.98 cubic inches (32.4 cc), the FS-200S generates 3.0 horsepower at 9,000 RPM. Its practical operating range from 1,800 to 10,000 RPM covers both relaxed scale sorties and spirited aerobatics.

Design choices that aid installation

The F-6010 muffler rotates through 360 degrees and can be set in or out to suit cowl shapes, and the reversible carburetor together with the narrow cam housing simplify fitting into different fuselage designs.

Fuel system and comparative gains

The FS-200S-P adds a PD-08 pump to ensure consistent fuel flow during inverted or extreme attitude flying. The larger carburetor intake and porting result in nearly 43% more power compared with the FS-120S-P.

The FS-200S Surpass is a sensible choice for pilots who want four-stroke character and extra thrust without major airframe alterations.
