Mapping Devo 8s switch to 6 & 8 Channel RX

Wonder if anyone can help with this. On the walkera RX802 it has two Aux channel mark Aux 2 and Aux3. It seem that only Aux 3 can be map to any switch on the radio. I can't get Aux 2 to map to any switch. But the channel is working has anyone had this same problem.

And with the 6 channel rx it has 1 Aux that mark Aux 1 but on the Devo 8s radio there is no Aux1 in the radio how do you use this channel. Again the channel is working but with the throttle control.

Any idea or help?

I'm still using the stock firmware. I cannot assign Aux2 to any switch it just won't work. Aux3 I have no problem with. Why can't I assign Aux2 to a switch.

Okay I tried it again and was able to get Aux2 to work don't know I couldn't get it to work before.

One other question the RX802 receiver also has a Aux1 but there is no Aux1 in the Devo 8s if I needed all three Aux channel would i need to upgrade the firmware and I'm speaking of the Deviation firmware as I don't my model Devo 8s can be upgraded.


Thanks for the help
