OS .12 CV-R

The engine of choice for serious off-roaders!

This engine draws from O.S.' many years of engineering expertise, with the result being an innovative power plant that's destined to dominate .12-sized racing. The .12 CV-R is packed with high-tech features that transform it into a real powerhouse. Three larger ports (instead of two smaller ones) significantly increase air and fuel intake, for greater and more efficient horsepower.

High-performance features include:

  • Crankshaft is 1mm larger, with a larger crank port that directs fuel mixture more smoothly
  • Larger crankshaft bearings and a beefier, machined aluminum con rod improve the engine's durability
  • The fit between the crankshaft and bearings is much tighter, which increases vacuum and crankcase pressure for added efficiency
  • 10E-R carburetor is especially well-suited for off-road cars, buggies and trucks
  • Full linear action of the 10A slide-valve carb offers more consistent throttle response throughout the rpm range
