*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.

Most reliable speed controller I've ever used, several years running, several of my trail rigs use this esc and see horrifying conditions,
The programming is super easy with or without the field card or the castle link

Do not be afraid of running 3s packs on this esc! And I would strongly recommend using castle connectors to keep that nasty mud and sand out
