Modelix Racing have released the new, OS based, 3 port .21 Off-Road M3X Competition engine by Ultimate Racing designed by the O.S team of engineers. The engine incorporates the following “Made in Japan” high precision steel rear bearing (that ensure high idle stability, longer life and low friction at high temperatures) and balanced crankshaft with tungsten weight and silicone filling.

The M3X is a square stroke, specifically designed for maximum power, performance and tunability. With this engine you will have a great and super smooth linear power from low to high R.P.M. Produced with the guaranteed OS quality, this is a cheaper option with the same power and performance than its predecessor, the M3T.

TECHNICAL SPECIFICATIONS of this Engine:

The cooling head of the Ultimate M3X Competition engine has been redesigned by Modelix Racing. The carburetor is the same mounted on the M3S and M3T engines where high speed needle holder has been redesigned for a better refrigeration of the fuel flow into the carburetor, lowering the temp of the carb, and as a consequence it’s more stable with a great idle stability, improves fuel mileage and overall engine performance.
The M3X engine has been designed by the O.S team of engineers to ensure an optimum flow of fuel thanks to the aerodynamic design and the silicone filling. It is balanced with a tungsten weight in order to increase the inertia to rotation.
