If there was no ground to the receiver, I would have no RC signal. I can read an RC signal and prove it varies. I can probe the signal pin and get the variance. The signal wire is red but wire color has nothing to do with it.
I have tried RC1 and 2 with no change. I get a change in the SMC if I use analog 1 and manually vary it.
Why no RC
it should be read continuously if I understand the manual.
It’s gotta be simple whatever it is.
