O.S. Engine OSMG0830 FS-30S Surpass Compact Power 4-Stroke Engine  [OSMG0830]

Compact 4-Stroke Gain with the FS-30S Surpass

The O.S. Engine FS-30S Surpass is aimed at model fliers who want increased performance from a small 4-stroke unit. It matches .26-size mounting standards and provides an estimated 20% power increase over the FS-26, alongside lower noise and improved fuel economy for similar installations.

Practical Benefits for Model Pilots

When used on airframes such as the Great Planes Piper J-3 Cub .20 or in a T-Craft, the FS-30S Surpass handles larger propellers to deliver stronger acceleration and a more realistic engine tone. Its ringed piston and rear updraft carburettor help maintain compression and throttle response, while the dual ball bearing crank and helix gear-driven camshaft offer dependable timing and smooth operation.

The O.S. Engine FS-30S Surpass is a compact, practical upgrade for those looking to improve climb and cruise on small models without extensive airframe changes. It suits both relaxed sport flying and light aerobatics.
