What battery options work best with this transmitter?

Use quality AA cells or the recommended rechargeable pack for stable operation. Choose cells with consistent voltage to avoid erratic stick behavior during runs.

The dual receiver design typically balances signals between modules for redundancy. Refer to the receiver manual for specifics on primary and backup behavior in your setup.

Place receivers away from motor esc noise and metal parts. Use foam padding and orient antennas to avoid parallel routing with high current wires for best reception.

Can I use the EX-NEXT with an external telemetry sensor?

Compatibility depends on the receiver and accessory interfaces. Check the KR-420XT documentation for supported telemetry sensors and wiring details before adding external devices.

What maintenance keeps the transmitter performing well?
