Channel 5 saturates

[AdamAppleton]

Any idea why channel 5 always saturates? Any analog control from my radio that I have assigned to channel 5 always acts like a switch to any analog controller axis (>= 1500 yields 0.97436 on gamepad tester, >1500 yields -0.98077 on gamepad tester).

I can see that my radio is outputting the correct 988 through 2012 for the analog control. I've changed the mapping and rebuilt, updated the CRFS libraries and rebuilt ... all produce the same behavior from channel 5.

I can't find anything in the code that looks like it would cause this.

I suppose it could be my ELRS Receiver that has the problem, but that seems unlikely.

ELRS is designed to use channel 5 as a two position arming switch. This documentation shows how different channels can be used.
