O.S. FS-200 Surpass w/F-6010 Sil.

The largest, single-cylinder four stroke engine that OS has ever made draws on unrivalled experience in engine design. This powerful, high-torque engine has been created with scale and sports-scale modellers in mind. The ability to turn a big propeller, yet offer compact external dimensions, makes the fitment inside the `tight' cowling of scale models a real joy. Fuelling is courtesy of a specially designed twin needle carburettor and like all the latest Surpass series, the internals have been lavished with the engineering care that only OS can achieve, whether that be precision machining, material selection or surface finish.
