O.S. FS52 Surpass

£169.95

One of O.S.'s most popular four strokes thanks to a combination of quality, performance and moderate price - plus the fact that it is designed for more economically sized, quick to build sport and scale models.
Its features include four ball bearings, with sealed rear bearing , plus plated cam and crankshaft for superior corrosion resistance.
Supplied complete with silencer, the FS52S is designed to be used with 10.5” x 8~9” to 12.5” x 6” propellers and has a similar power output to many .40 size two stroke motors.
