I’m running a Pixracer with ArduPlane V3.7.1.
I was unable to get the servo output working so I connected Ch.1 to the Arduino to read the raw PWM output.
Here’s what that looks like:
Here’s what I’ve done so far:
Connected external 5V power source on output rail
Configured plane as AERT
Set MANUAL mode
ARMING_REQUIRE=0, for good measure
Confirmed RC transmitter values being read in groundstation
The PWM value from the Roll channel on my transmitter will be sent to Ch1 of the output.
PWM value = 0.
Would appreciate any help here.

Additional input on the issue, note that the expected outputs are consistent with the RC input:
However, the observed PWM output is 0 for all servo channels.

@unmannedtech1 I got this from you guys a week or so ago. Would appreciate your feedback. Thanks
Dont know if you have done this, but are you using the safety switch as pixhawk will block any pwm outputs untill the safety button is pressed?
Also what is your status led doing on the board? Is it flashing slowly?

I did use the safety switch, though
it’s optional on the Pixracer and has no effect when
ARMING_REQUIRE=0 … No luck.
The power LED is solid green. The status RGB LED is off, probably because it
may still be unsupported on Arduplane. I’ve tried flashing the PX4 firmware as well, but the results are the same (no servo output).
