I’ve got an XD 470 loader from China with a Flysky i6s radio. Tried running it today with a freshly charged 3S lipo ( recommended) and fresh batteries in the radio. After turning on the Tx then plugging in the battery, I get on RX power showing on the TX screen but my loader’s rotating light works. Why doesn’t my RX power show “on” when the lipo is plugged in?
