The KO Propo 30143 - RSx4S-Response H.C is selected by modellers who prioritise consistent control. As a replacement servo it delivers accurate movement that keeps steering inputs faithful to your transmitter commands.
With its reliable construction, the RSx4S-Response H.C offers repeatable performance that suits both club competition and serious hobby use. It reduces unwanted play and helps maintain a stable steering feel lap after lap.
Mount the servo cleanly and check that the horn is centred before finalising linkages. Regular inspections of cabling and connectors will prevent intermittent faults and preserve response quality.
