OS developed the Surpass Series of 4-cycle engines for discerning fliers who demand more power. All Surpass engines feature a helix gear driven camshaft on the front end and newly designed updraft carbs in the back. Enlarged intake valves and stronger working parts yield superior compression and improved output in the power stroke. OS Surpass 4-cycle engines provide the best performance for your plane, regardless of scale or flying style.
The FS-120 Surpass E is the basic suction-feed version of the FS-120 series, without fuel pump or pressure regulated carburettor, but with all the other quality features found in the FS-120S series engines, which, at 20cc, are the largest single-cylinder engines in the OS four-stroke range. Excellent for sport flying with large models and for scale models where the fuel tank can be located normally. Muffler and glow plug included.
