ProTek RC CR21 3-Port .21 Offroad Engine

ProTek RC has announced its new CR21 3-port .21 off-road engine with the same DNA as its highly successful Samurai engine line. The budget-friendly ProTek CR21 features a newly designed crankshaft to improve engine response and a lightweight piston that further assists with a crisp engine response on throttle input. The combustion chamber design optimises low to medium RPM ranges, perfect for newer racers, while still offering high performance output at high speeds for more experienced drivers. And it is easy to tune and stabilise with a 2-needle carburetor with 6mm and 7mm inserts available.  An “EBIS” version of the ProTek RC CR21 is also available, featuring the engine break-in services of RC racing and industry legend Adam Drake.
