Ultimate Engine M3R 3.5cc nitro off-road engine

Modelix Racing have introduced their new M-3R 3-port 3.5cc nitro off-road engine. Like the previously released M3S, the R version is a 3-port 0.S. based power plant but it features a high-precision and Japan-made rear steel bearing, a balanced crankshaft with tungsten weight and silicone filling and it comes with a 6.5mm venturi insert. The engine is of a long stroke design, it offers high torque and extreme power all combined with low fuel consumption. Other features include a low-profile cooling head designed by Modelix, the carburettor is the same as with the M3S and M3T engines and the backplate is machined from 7075-T6 aluminium with the hard material reducing the conrod/backplate friction.
