The RUDDOG RNX21.3 3.5ccm Nitro Off Road Competition Engine is Ruddog's first high-performance nitro off-road engine. The high-quality 3.5cc competition engine features a 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 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 chamber insert keeps dust away from the delicate parts of the engine. The engine is rounded out by a gold-colour cooling head whose standard height allows to run the engine leaner, extracting ever greater mileage from the engine.
