Yokomo BL-RS4 Drift Spec Sensored Brushless ESC/Zero S Drift Spec Motor Combo

The Yokomo BL-RS4 Drift Spec Sensored Brushless ESC and ZERO-S Drift 13.5T Motor Combo pairs drift-focused throttle control with smooth, consistent power for 2WD and 4WD applications.

Drift-Spec ESC

The BL-RS4 features a full aluminum case and drift-specific programming. Its low-speed throttle response is set to mild for easier drift-angle control, while the middle-speed range receives additional boost for powerful cornering. The sensored, 4-pole brushless ESC also includes a built-in DC booster, selectable 6V/7.4V BEC output, and a “Boost 0” mode.

ZERO-S Drift Motor

The ZERO-S Drift 13.5T sensored brushless motor delivers increased torque and smooth throttle response through the low-to-mid throttle range. Cooling vents in the motor case help promote cooling, and the motor wires are soldered in place.
