This is the Novak Crusher 2S-4S Crawler Brushless Motor Combo, with an included 21.5 Turn Ballistic Crawler motor. Rock Crawling has become more than just getting across tough terrain the safest way possible. Rock races, tough truck challenges, and various forms of ultra and ultimate 4x4 formats have created a demand for a wide range, high powered, compact system. The Crusher crawling combo is here to answer that call! The combo includes Novak’s Crusher ESC with all of the proven Novak rock crawling features you demand, like powered hill brakes, instant reverse, and full-time sensor-based performance for unmatched low- speed throttle response and power. Add to that a completely rebuildable Ballistic Crawler Brushless Motor, and a system that comes ready to install out of the package, and the Novak Crusher Crawler Combo has everything you’ve been looking for!

The Crusher is race-ready with a built-in 5-amp BEC, wide 2S-4S voltage range, and enhanced Novak X-Drive firmware upgrades. Novak crawling ESCs have the most powerful hold/hill brakes in the industry, and the Crusher features Power Brake settings that will hold even the heaviest crawlers on the steepest of inclines. When you are done scaling tough descents and need to get to the next obstacle or down the trail faster, the Crusher utilizes Novak’s RPM Boost Timing for added RPM and top speed. The Crusher’s sealed case design, complete coverage heat sink, and included cooling fan ensure you can thrash on your rig run after run.

Novak takes pride in its manufacturing facility in Irvine, California and also with its use of high-quality components and assembly and testing processes. Each Novak Crusher Crawler Brushless System is built and tested in the Novak factory to Novak’s exacting standards. All Novak products are supported by Novak’s knowledgeable customer support staff and race team.
