Get wet!
Castle’s Sidewinder ESC, the leading 1/10th scale sport brushless ESC, is now waterproof. The new Sidewinder 3 can power crawlers on water filled trails, SCTs through rain soaked parking lots, and AWDs on rips across muddy fields. Drivers can follow their irresistible urges to drive in the mud or stomp their truck in puddles without damaging their controller.

Designed for 1/10th
The Sidewinder 3 ESC is a great fit for 1/10th off-road, on-road, and rock crawlers running up to 3S LiPo*. It sports updated circuitry for faster response time and improved reliability. As always, the Sidewinder 3 offers industry-leading software functions and USB programming capability via Castle Link USB adapter (sold separately).

Legal mumbo jumbo
Although Sidewinder 3 and Castle brushless motors are waterproof, always rinse the ESC and motor with fresh water after exposure to corrosives or dirt. While the motor and controller may be waterproof, we suggest users confirm that the rest of their vehicle, including the batteries, servo, radio and chassis, are also waterproof before exposing them to liquids of any kind.

Note: product labeling and wiring may not match the images shown here.

*We recommend using a BRUSHED motor 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.
