RUDDOG RNX21.3 3.5ccm Nitro Offroad Competition Engine

The RNX21.3 is RUDDOG Distribution’s first high-performance nitro off-road engine. The high-quality 3.5cc competition engine features as specially developed crankcase for exceptional performance and great fuel economy with a rear ceramic main bearing and a DLC-coated and Tungsten-balanced crankshaft ensuring very high power output and reliable performance. The engine is of a 3+1 port long-stroke design for high yet controllable torque especially in the lower RPM ranges, making it ideal especially for smaller or technical tracks. Other features include a 22D carburetor for smooth throttle response and high fuel economy while an O-ring equipped combustion camber insert keeps dust away from the delicate parts of the engine.
