Accurate control from the KO Propo RSx4S-Response H.C Servo

Engineered for drivers who want precise input, the KO Propo RSx4S-Response H.C Servo with Selector4S offers crisp motion and repeatable centring. Its construction emphasises quick responses and stable tracking during competitive runs.

Selector4S lets you tailor servo behaviour

The Selector4S system enables rapid changes to response curves and centring so you can optimise handling for different surfaces. Minor setup changes can noticeably improve turn-in and on-power stability.

Where this servo fits in your fleet

Designed primarily for 1/10 scale cars and buggies, this servo is a strong choice for touring, pan car and off-road classes that demand sharp steering control. It integrates well with common radio systems and mounting patterns.

Remark :
Due to limited stock availability, please notice that some KO Propo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this fit standard 1/10 servo mounts?

Yes, the unit follows common 1/10 mounting dimensions and will bolt into most servo trays without modification. Confirm horn clearance and servo saver fit before final installation.

Do I need a brushless servo tester for setup?

A simple servo tester or your transmitter will suffice for initial setup. For advanced tuning of the Selector4S settings, use your radio to tweak endpoints and subtrim for optimal geometry.

How durable is the servo under regular racing use?

The RSx4S-Response H.C is built with durability in mind for typical club and regional racing. Regular inspection of gears and mounts is recommended to maintain long term reliability.

Is there any recommended maintenance?

Periodically check mounting screws, horn tightness and wiring. Keep the internals free of grit and replace the servo if you notice play or inconsistent centring.
