Sidewinder 4, 2-3S, 2A BEC, WP Sensorless ESC P-CC010-0164-00

The all new and improved Sidewinder 4 builds upon Castle's most popular platform - the Sidewinder 3.

The Sidewinder 4 is the first 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.

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 or paired with a Castle Creations 4-pole brushless motor. It can also be used in a rock crawling applications with a brushed** motor down to a 19 turn.

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.

**Brushed motors are recommended for rock crawlers (vehicles traveling 3-5mph.) Brushless motors are fine for use with rock racing. If your vehicle is going to be in a bound up situation, very slowly traversing rocks and obstacles, you are running a rock crawler. If you are constantly travelling at 5mph or higher, you have a rock racer.
