I'm flying the latest FW on a PixHawk and need a PWM signal that (preferably) is the average of all the other PWM (Servo) outputs. I flying a quad, so Servo 5 is available.
In MP, there is an option to set SERVO 5 to "Throttle" using option "70", but I find that doesn't give me any signal at all. I can't simply use the normal throttle input, because I want the signal to be valid in all modes (including AUTO). Does anyone know how I can get this output without modifying the FW?
