This combo is a Mamba X ESC and 1515 1Y 2200kv motor for lighter 18th scale applications. Normally this motor is paired with the 18th scale Mamba Monster X ESC; but if you need to save some weight or need a smaller footprint, the Mamba X is more than capable of running this motor. This setup is recommended for 3s or 4s use in a vehicle weighing less than ~9lbs and geared for no more than ~45 MPH.
