This is the Castle Creations Sidewinder 3 Waterproof 1/10 Sport ESC. Castle’s Sidewinder ESC is now waterproof! The Sidewinder 3 can power crawlers on water filled trails, AWDs in rain soaked parking lots, and SCTs on adventures through muddy fields. Drivers can now give in to those irresistible urges to drive in the mud or rip through puddles without damaging their ESC.

Designed for 1/10th
The Sidewinder 3 is a great fit for 1/10th off-road, on-road, and rock crawlers running up to 3S LiPo. It features 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).

Amazing Price
The Sidewinder 3 offers world class performance at an entry level price.

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, Castle suggests 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.
