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

The Yokomo BL-RS4 Drift Spec sensored brushless ESC is paired with a purple ZERO-S Drift 10.5T motor for RC drifting. The ESC uses drift-specific programming with mild low-speed throttle characteristics and added mid-speed boost to help control drift angle through corners.

The full aluminum case also serves as a heatsink, while the sensored motor provides smooth throttle response from low to mid throttle. The motor features cooling vents and pre-soldered motor wires, making this combo suitable for beginner through advanced RC drifters.
