This Castle Sidewinder SCT Waterproof Combo includes the Sensored 1410 3800Kv Motor and is a great choice for 1/10 scale short course trucks up to 6.5 pounds on 2S, as well as 1/10 buggies and trucks up to 4 pounds on 2 or 3S. The Sidewinder SCT is Castle’s solution for anyone who needs an unbeatable combination of power and affordability in a special edition controller and motor combo made for Short Course Truck racing. While the sensored capabilities of the motor cannot be utilized with the Sidewinder SCT, users will benefit as the sensored motor is rebuildable, and this design even allows modelers to replace damaged motor wires. The Sidewinder SCT Combo will give you great response and performance right of the box! The ESC (electronic speed control) offers power to spare at 2-3S LiPo, and a waterproof case that can perform in just about any environment. 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. Although Sidewinder SCT and Castle brushless motors are waterproof, they are not intended for operation while completely submerged in liquid. 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. The cooling fan must be removed prior to driving in wet conditions. It is not waterproof. Sensored capabilities of the motor cannot be utilized with the Sidewinder SCT. If you require sensored operation you will need a sensored ESC like the Mamba X. The Mamba X paired with the same motor can be found here.
