*Not intended for operation while submerged in liquid. If unit is operated in wet conditions, rinse with fresh water to remove dirt or corrosives, then fully dry unit.

**Brushed motors are recommended for rock crawlers (vehicles traveling 3-5mph.) Brushless motors are fine for use with rock racing. If your vehicle is going to be in a bound up situation, very slowly traversing rocks and obstacles, you are running a rock crawler. If you are constantly traveling at 5mph or higher, you have a rock racer.
