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 1406-7700Kv sensored* motor. The 1406-7700kv 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.
