There is one ELRS mode: 16 Channel Full rate/2 that will give you a full channel 5, but you really don't want that because only works with a limited few combos of packet rate/telemetry rate. You just have to assume with ELRS that Channel 5 is 2 position arming, but the bonus with that you get is that is guraranteed to be sent to the FC in every single radio packet no matter what, so ArduPilot needs to be set to not use Channel 5 for anything except arming.
Andy, thanks for posting this. It is not clear to me what the hang up with RC5. Were you experiencing a low-power limit with ELRS as a result of not having arm on the is switch? And what if I just rely on arming by pulling throttle back and to right. Do I really need to rely on a mechanical switch for arm/disarm. I don't like this because of the possibility of accidental disarm during flight. Please advise if you have the time - do I need to arm with RC5 on ELRS?

No you don't, but you need to remap RC5 on your transmitter since usually that is the mode switch.
