Big slither.

Meet the next big kid on the block. Lean and mean like his little Sidewinder 3 brother, he features everything you’ll need to toss around buggies, truggies, and monster trucks like a rag doll. Anything weighing in at up to 11lbs and running up to 6S LiPo is fair game. It’s powerful BEC will laugh at nearly every servo on the market today, and it’s potted design will tolerate wet conditions without flinching. Paired with Castle Creations new 1515B-2200kv motor, featuring the same internal design as our award winning NC-1515-2200 motor, it’s sure to beat down the competition. The ESC is equipped with the state of the art software that Castle is known for and has USB programming capability using the Castle Link USB Adapter (sold separately). So pound on snow filled parking lots, beat the muddy trails into submission, and tear streams a new one. Tell ‘em Sidewinder 8th sent ya.

Legal mumbo jumbo that we need you to read:
Although Sidewinder 8th and Castle brushless motors are waterproof, they can corrode when exposed to corrosive materials, such as salt water. Always rinse the ESC and motor with clean 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, servos, radio and chassis are also waterproof before exposing them to liquids of any kind.
