This is not just a cool looking engine, nor is it "just" an addition to the Axial RR Performance Series of engines. The Axial 21RR-1 Engine has vast improvements with such features as a rock solid 2-needle carburetor, balanced crankshaft, 7-port piston cylinder sleeve and all new designed crankcase with emphasis on strength and weight reduction.
The Axial 21RR-1 carburetor has the stealth blacked out looks built with simplistic 2-needle design for ease of use. Color coded aluminum venturis in increments of 6.5mm, 7.0mm and 8.0mm are supplied to use in conjunction with the stock carburetor [9.0mm inlet] allowing for a wide range of airflow velocity tuning capabilities. Fully adjustable fuel valves and carb-linkage allow this carburetor to work on various engine applications. Another "performance-look" feature is the visual markings on the carburetor indicating 1/16th increments allowing for an "easy to adjust" air-fuel needle.
Axial engines are dyno tested to ensure the highest level of performance possible. We use the highest quality materials and the latest CAD and CNC techniques to set the maximum level of quality possible at roughly half the cost. The Axial 21RR-1 engine is aimed to provide the perfect balance between performance and price to deliver the top overall value for the enthusiast that likes to run hard and spend a little. If you are looking for "the best bang for the buck nitro engine" the Axial 21RR-1 is for you!
