Alpha RC's new range of well priced, high quality, high performance engines have been incredibly well received throughout the world on there debut. Despite Alpha RC being a very new company to the RC industry the foundation of the company is built on many years of nitro engine research, development and expertise. Consequently, since there original debut each and every one of Alpha RC's range of engines have been very highly regarded by racers of all levels. 

The Alpha Plus F850 is the ideal club racer engine, featuring a 5-Port construction the engine provides excellent bottom end to mid-range power, with a good amount of top end RPM. Overall however the engine feels rather linear, controllable and retains a good fuel economy over its quicker counter parts in the same range. This then would make an great choice for 1/8 buggies for use on small tracks, or drivers just initially stepping up to the power of a true .21 race engine. 

Each engine comes complete with a 0.10mm head shim which is necessary for operating the engine on 30% fuel and a set of 2 alternative carb restrictors, to help further tune the engines power and economy.
