Ultimate Racing M3S nitro off-road engine

Modelix Racing have introduced the new Ultimate Racing M3S nitro off-road engine. The O.S. made long-stroke power plant was developed to combine high torque with extreme power and a low fuel consumption, something that was achieved by using a redesigned carburettor that sports a new high speed needle holder for optimised mixture flow, better idling stability and increased mileage. Furthermore the new carburettor features a new uniball joint with two mounting screws for easier angle adjustment. Also new is an updated crankshaft with silicone filling and tungsten balancing while the DLC coating improves the lifespan of the crankshaft and crankshaft pin. Part of the new package is also a 3-port liner and piston assembly for smooth, linear yet high power supply and the updated CNC-machined and red anodised backplate made of 7075-T6 aluminium for reduced friction. Thanks to its design the backplate is now also easier to remove. The M3S engine is rounded out by high-quality Japanese-made ceramic bearings and 6.0mm and 6.5mm venturi inserts.
