Motor Recommendations

Looking to get a brushed motor for your rig, but don’t know where to start? Too many choices got you dizzy in the head? This guide will help you make a motor selection and ensure you get what you need and gear it properly!

Are you just starting out and don’t know what to get? Select a 55t TorqueMaster. 20t CrawlMaster, or 2200kv brushless for slow going and long run times or a 27t TorqueMaster, 13t CrawlMaster, or 3300/3500kv brushless for more power and wheel speed.

Don’t let your motor temperature get over 160°F (70°C) for best motor life! When in need of more speed, volt up and gear down instead of increasing the pinion size.

Purchasing for a child new to R/C crawling and trail running? The 55t TorqueMaster 540 Expert motor for crawling is our best suggestion. It is not overly powerful on 2 or 3s LiPo and is less likely to break parts. Faster (lower) turn counts, Pro series brushed motors, and brushless motors can break parts more easily. Beware of the power!

Below is a list of motor turn counts and speeds. Motors on the same line have equivalent speeds.
