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.

Does the EX-RR ST2 support multiple model memories?

Yes, you can store several model setups on the transmitter so you can switch between cars or configurations without reprogramming each time.

Are there recommended antenna routing tips?

Keep the receiver antenna clear of metal and power wires, route it straight where possible and avoid tight coils to preserve signal strength and reduce interference.

Can I revert settings after a poor tune?

Save baseline profiles before making changes so you can quickly revert if a new tune degrades handling, and use small steps when adjusting parameters.

Is the KR-415FHD suitable for foam tyre setups?

The KR-415FHD performs consistently regardless of tyre choice; focus on tuning steering and throttle maps to match the grip characteristics of foam tyres.
