O.S. Engines Pump Ring 70N Carb (OSM35540) | RC Planet

Building the 4-Stroke of the future, one engine at a time! Surpass engines share features that include a helical gear-driven camshaft up front and a reliable rear updraft carb. Generous intake valves and CNC-machined parts add superior fit, power and compression. Rugged ringed pistons and ball bearing-supported crankshafts contribute smooth, trouble-free operation. Most also include rubber-sealed ball bearings, a reversible carb for easy installations and corrosion-resistant plating on the crankshaft, camshaft and piston. High torque for spinning bigger props. Quieter, more realistic airplane sound. Generous with power — stingy with fuel.
