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.

What voltage range gives the best performance?

Running the servo at the upper end of its rated voltage, around 7.4V, provides the quickest response and maximum torque. Ensure your receiver and BEC can supply a stable voltage under load.

Is the Selector4S easy to adjust trackside?

Yes, the Selector4S is designed for quick setting changes so you can alter the servo feel between runs without major disassembly. Keep small tools on hand for fine tuning.

Can this servo handle heavier steering loads?

With 13.0 kg-cm torque at 7.4V, the servo handles common steering loads on 1/10 scale vehicles. For unusually heavy setups, check horn leverage and steering geometry to avoid overloading the unit.
