Modelix Racing have added the new M3R nitro engine to the Ultimate Racing range of engines. The M3R, like the M3S, is a long stroke, high torque and extreme power engine with low fuel consumption. Unlike the M3S, the M3R incorporate the following parts: high precision steel rear bearing made in Japan, balanced crankshaft with tungsten weight and silicone filling and 6.5mm plastic venturi. Also made by the prestigious Japanese O.S. brand, the M3R is a cheaper option with the same power and performance than its predecessor.
