The KO Propo 61032 - 4S Servo Model Selector helps pilots and drivers confirm the correct BSx4S servo model for their application. It removes ambiguity when pairing servos and radio settings, making it easier to get predictable control response from your rig.
Whether you run on smooth asphalt or technical tracks, the selector helps you manage different BSx4S servo setups. It is useful for teams and solo drivers who switch builds often and need a fast method to validate servo selection.
Designed specifically for the BSx4S line, the KO Propo 61032 focuses on direct compatibility to prevent mismatches. That focus ensures you can rely on it when tuning steering, throttle, or other servo-controlled functions.
