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, we’ve got you covered! This combo includes a Sidewinder 4 ESC and 1406-6900Kv sensored* motor. The 1406-6900kv motor is a great upgrade for 1/10th scale on-road cars for 2s use. It can also be used in some lighter off-road 1/10th stadium trucks and buggies with conservative gearing. NOT for use in 2WD or 4WD short course trucks. Please refer to our Gearing Chart for recommended motor, battery and gearing for some of the more popular vehicles on the market.

* Sensored capabilities of the motor cannot be utilized with the Sidewinder 4. If you require sensored operation you will need a sensored ESC like the Mamba X. The Mamba X paired with the same motor can be found here . **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.
