The Sidewinder 8th is Castle’s latest indulgence in affordable power upgrades for 1:10th scale Monster Trucks and 1/8th scale buggies, truggies and onroad vehicles. This combo provides all the power and muscle that Castle is known for at an exceptional price point. This system is designed for use in R/C vehicles weighing 11 lbs or less, with batteries and ready to run. It’s a popular upgrade that performs flawlessly at up to 6S (25.2 volt) operation (stock gearing required in E-Maxx/E-Revo) and sports a brawny 8amp peak BEC. We think you’ll like utilizing stronger servos, because this means powering up your torque or increasing steering response! The ESC has a potted design and will tolerate wet conditions without flinching, so pound on snow filled parking lots and beat the muddy trails into submission, this system is ready for the challenge. (*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. Fan is not water resistant. Remove fan from ESC before exposing vehicle to liquids.) Like all Castle controllers, the Sidewinder 8th may also be “tuned” for the drivers’ preferences in the throttle curve, brake strength, reversing modes and more. Access these features through your PC by purchasing the Castle Link USB connector , sold separately. The Sidewinder 8th controller is paired with a 1515B-2200kv motor that sports the same award winning internal design as the Castle 1515-2200kv. It sports high quality components resulting in a highly efficient motor, ready to give hardcore R/C enthusiasts the Castle advantage.
