Castle Creations Sidewinder 4 sensorless ESC


Castle Creations have introduced their new Sidewinder 4 sensorless speed controller. The all new and improved Sidewinder 4 builds upon Castle’s most popular platform, the Sidewinder 3. The Sidewinder 4 is first Castle’s platform running Cryo-Drive technology which reduces operating temperatures in all applications. Cryo-Drive is a potent combination of software enhancements and precision fluid dynamics.

The new case is designed specifically for maximum airflow from the huge 30mm fan included with the Sidewinder 4. These changes result in cooler ESC temperatures, increased runtime and power handling. All of these improvements mean you can gear more aggressively for more speed and harder/longer runs. And of course it is still waterproof and compatible with the optional Castle Link USB programmer. The Sidewinder 4 is a versatile ESC that can be used in a wide variety of applications. It is available by itself our paired with our 4-pole brushless motors; it can also be used in a rock crawling application with a brushed motor down to a 19 turn.
