French company RC Concept have introduced their all-new MC5R 3.5cc nitro off-road engine. Developed and tested in cooperation with drivers such as Reno Savoya and Lee Martin, the engine delivers enhanced runtime, reliability and power thanks to an improved carburettor that makes for better mileage and mid-range power and a new Turbo plug piston head for improved temperature stability. A redesigned sleeve makes for more torque and better fuel economy while the new gold-colour cooling head helps with stable temperature management. The engine is rounded out by a new 8mm venturi insert for increased runtime and power.
