CrawlMaster Magnum Stubby 20t


CrawlMaster Magnum 540 20t- High torque, smoothest startup, lightweight and small! .

Please allow 2 weeks for assembly and manufacture. These are currently made to order.

The Magnum is a performance oriented brushed motor designed with a larger rotor diameter and more powerful Neodymium magnets, when compared to the regular TorqueMaster and CrawlMaster Pro 540. This motor was born out of prototype work for our team drivers and a love for the hobby. The "Stubby" version is smaller and lighter, specifically for competitive drivers who want top performance in a small and light package
