Team Orion have two new .21 nitro competition engines for off-road and on-road applications available. Starting with the buggy engine, R21 Racing Team V2 is the evolution of the popular buggy 3-port racing team and it received some subtle updates such as a black-coated 60mm diameter cooling head for improved heat dissipation and lower running temperatures. Also new is a redesigned piston that leads to a higher RPM range. The case is black coated for a better heat dissipation and the head now features a 60mm diameter same as our factory versions for a lower running temp and increased mileage. A new designed piston ensures higher rev. The R21 Racing Team V2 offers the best quality/price ratio from our range of engines.
