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.

Is this compatible with my 1/8 touring car?

Yes. The RSx3-Response H.C is a standard size servo suitable for 1/8 touring and buggy applications when your mount accepts the standard footprint.

Will the aluminium top case prevent overheating?

The aluminium top case helps dissipate heat better than plastic covers, supporting longer high-load runs, though proper airflow and correct voltage selection remain important.

Can I use this with a gyro or stabiliser?

Yes. The servo's fast response and clean connector make it suitable for setups with gyros or stabilisers, provided the control system supports standard servo signals.

What maintenance is recommended?

Periodically check the gear mesh and mounting screws, keep the connector clean, and replace worn servo horns to preserve performance and bearing life.
