Sidewinder 4, 2-3S, WP ESC with 1406-5700Kv Motor 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.This combo is ideal for general bashing with 1/10 2WD stadium trucks and buggies and includes a Sidewinder 4 ESC and 1406-5700Kv sensored motor. The 1406-5700Kv motor is a great motor for 2WD short course trucks on 2S LiPo and geared conservatively. It makes a great combo for 1/10th 2WD Stadium trucks and buggies on 2S for general bashing and limited runs on 3S: temperatures will climb quickly on 3S. It makes a great upgrade for 1/10th scale on-road cars for 2S and 3S use. NOT for use in 4WD short course trucks.Sidewinder 4 combo includes:Sidewinder 4 ESCCastle 1406 1Y 5700 Kv sensored motor Quick Start Guide1/10th scale gearing chartDecal sheetSensored capabilities of the motor cannot be utilized with the Sidewinder 4.
