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, Castle has you covered!

This combo includes a Castle Sidewinder 4 Brushless ESC and Castle 1406-4600Kv Brushless Sensored* motor. The 1406-4600kv 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.

* Sensored capabilities of the motor cannot be utilized with the Sidewinder 4 Brushless ESC. If you require sensored operation you will need a Brushless Sensored ESC.
