PROTEK RC ANNOUNCES NEW CR21 3-PORT .21 OFF-ROAD ENGINE featuring the same DNA as Successful ProTek Samurai Line but Suggested MSRP Under $300.

ProTek RC is announcing its new CR21 3-port .21 off-road engine with the same DNA as its highly successful Samurai engine line, but with a suggested retail price of less than $300. The budget-friendly ProTek CR21 is now available at AMainHobbies.com or through your local track store or hobby shop.

The 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.

And it is easy to tune and stabilize with a 2-needle carburetor with 6mm and 7mm inserts available.

An “EBIS” version of the ProTek RC CR21 is also available at amainhobbies.com, featuring the engine break-in services of RC racing and industry legend Adam Drake.
