RE: Spektrum AR6200 and DX6i
the RX will blink when bound to your TX after a power recovery of brown out. Make sure you turn off the TX after you power down or unplug the RX battery. Then turn the TX back on before powering up the RX again.
I have a DX6i and a couple ar6200s and they work just fine. There's nothing wrong with the AR6200 and DX6i combo. Just make sure you are using it correctly.
