The Sidewinder 4 is our first platform runningCryo-Drivetechnology which reduces operating temperatures in all applications.Cryo-Driveis 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.

PROUDLY DESIGNED AND MANUFACTURED IN OLATHE, KANSAS, the NEW SIDEWINDER 4 is backed by Castle Creations' 1-year warranty and unparalleled ”make-it-right' customer support. **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 traveling at 5mph or higher, you have a rock racer.
