 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.

Sidewinder 4 combo includes:

• Sidewinder 4 ESC
• Castle 1406 1Y 6900 Kv sensored* motor
• Driver's Ed and Guide Start Guide
• 1/10th scale gearing chart
• Decal sheet

Sensored capabilities of the motor cannot be utilized with the Sidewinder 3. If you require sensored operation you will need a sensored ESC like the Mamba X.
