RC4WD 540 Crawler Brushed Motor (45T)
This motor has outperformed my Titan 21T by a long shot! My first run with 2.2s was with the Titan and it instantly smoked itself lol. This motor I’ve had since September 2020 and it’s been great. I’ve submerged it a few times in water, gotten plenty of sand in it and it just keeps going. It’s obviously slow since it’s a 45t, but what do you expect. If you are replacing a motor on a budget, get the Holmes CrawlMaster Sport 13-16t or TrailMaster sport 21-35t, they are about $25-$30, it they will be way smoother and more controllable. But this motor is still good!

My old motor was too noisy and burned up my batteries too fast. Thought this would be a good choice. Motor burned up within 10 minutes of using.
