CrawlMaster Magnum 540


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

The CrawlMaster Magnum 540 motor has high torque and the smoothest startup of all of our brushed motors.

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.
