The Holmes Hobbies CrawlMaster Magnum 540 Brushed Electric Motor is a high torque, 11 Turn option that offers the smoothest startup of any Holmes motor, with faster wheel speed than a TorqueMaster Pro 540 27t.

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 is fully rebuildable and compatible with many Holmes 540 motor end bell parts.

Holmes Hobbies CrawlMaster Magnum 540 Brushed Electric Motor (11T)
Only about 30-45 minutes of run time so it took a while to notice that the motor shaft is off of its axis just enough to ruin pinion gears. When trying to adjust, it is to tight for 1/2 a turn and to loose on the other 1/2 of the rotation. I had to go back to the stock motor. It has a 1 year warranty from Holmes but I've been told their service department is unbelievably slow. I bought it through A-main so I don't know what to do. It should be perfect for what I paid for it. Extremely disappointed with the purchase. For the price, I should have just went with a brushless set-up. Guess I'm just out $150.
