This is the Castle Creations Sidewinder 4 12.6V, 2A BEC, Waterproof Sensorless ESC. While the all new Sidewinder 4 builds upon Castle’s most popular platform, the Sidewinder 1:10 Scale Series, it is the first of its kind to run Castle’s newest technology, Cryo-Drive. Cryo-Drive combines technology from cutting-edge hardware and software advancements to increase thermal performance. Cooler temps mean longer runs and more power in your Sidewinder 4 setup. The Sidewinder 4 is a versatile ESC and is accepted in a wide variety of applications. Whether throwing dirt, ripping through a corner or steadily dominating the trails, Castle has you covered!
