O.S. FSa-56 w/F-4040 Silencer
The new FSa-56 from O.S. is the first engine in a completely new series of advanced four strokes. The FS `Alpha' series draws on the experience gained from the Surpass range to develop and refine standards to a new level. The increased capacity compared to the FS-52 Surpass means more power/torque and the new carburettor provides even better throttle control across the entire RPM range! There are innovative features like incorporating the crankcase breather/oil recirculation system into the crankcase to dispense with external nipples and drain tubes as well as a dramatic & futuristic style. An effective and versatile silencer is supplied as standard.
Specification Capacity: 9.32cc / 0.569 cu.in. Silencer: F-4040 Propeller Range: 13x6-7 12x6-8 13x6 Weight: 419g/14.8oz w/o silencer Bore: 24.0mm / 0.945in Stroke: 20.6mm / 0.811in
