Single Copter with Pixhawk 4

Hi everyone, I am attempting to design a Single Copter using a Pixhawk 4 as the flight controller. I have read the documentation here - ArduPilot Single Copter. I understood all the configuration steps with regards to selecting the FRAME_CLASS and setting other parameters. However, I am uncertain as to whether the SERVOx_FUNCTION maps the output to the I/O PWM OUT or the FMU PWM OUT port on the Pixhawk.

Any feedback is greatly appreciated, thank you.

Outputs 1-8 are on the I/O outputs, 9-14 are on the FMU outputs.

Thank you very much!

So I need to wire the flaps to Outputs 1-4 and the motor to output 5 correct?

I’m not that familiar with Single Copter having never built one but from the Wiki that’s right.

Thank you for the information, very much appreciated.

You may have already found your answer since last week, but yes 1-4 are for flaps and 5 is for the esc.
