Holmes Hobbies CrawlMaster Pro Motor 540 Brushed Electric Motor (20T)
I got one of these for my Axial Capra. I have it paired with the Holmes Brushed ESC. As the motor was out of stock for quite a while, I'd used an Axial 35t motor to start. The difference between the two is remarkable. While top speed is about the same, the low speed control is completely different. The Holmes motor can barely move enabling incredible control. Lines I wasn't able to do before can now be done as I don't spin the wheels beyond traction at minimum control as the basic Axial motor did. The hype is real... even though I'd heard amazing things about Holmes motors, actually trying it myself has made me a true believer.
