Italian company Reds Racing have introduced their new M7 WCS Diamond Edition 1/8th nitro on-road engine. The 7-port extra long stroke engine is based on the M7 WCS 3.0 power plant and it features a new DLC-coated crankshaft, a new carburettor, a new cooling head and Reds Racing’s anti-dirt sealing system. The DLC-coated crankshaft and backplate will make for improved engine durability while the on-road specific carburettor provides greater idling stability, more precise tuning and improved power delivery. Furthermore the engine comes with a brand new cooling head which features an new design for improved airflow, resulting in increased cooling and a lower centre of gravity. The new cooling head is also lighter than the standard ones. Finally the cooling head’s anti-dirt sealing system keeps the engine clean in a critical area between the cooling head and crankcase. The redesigned crankcase also provides easier maintenance and a cleaner engine for longer life.
