Hello DIYD Masters!
I'm setting up a new Pixhawk, and when I go to calibrate the radio, channel 4 is missing. I'm using mission planner 1.3.1. Channel 4 servo also doesn't respond as if it isn't connected, however when I connect the servo directly to the receiver, it behaves normally. Strange! Did I miss something in a recent update? I've attached a screen shot of what I'm seeing.
Thank you for any tips you can provide!
