Product description

Building the 4-Stroke of the future, one engine at a time!

Surpassâ„¢ 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.


O.S. Engines two year limited warranty
  • High torque for spinning bigger props.
  • Quieter, more realistic airplane sound.
  • Generous with power — stingy with fuel.
