No servo working YRRC miniPX4 Arduplane V4.09

Hello everyone
I’m new here so let’s just hope I don’t do anything stupid.

What do I have.
A YRRC mini PX 4 from BG. Installed it for arduplane, at data/messages I see V4.09.

What did I connect for the test. The FC board YRRC, the GPS, the receiver X8R, a servo and the ESC. I have 5 Volts on the + of the output through the ESC, and a servo.

I have connected the receiver with SBUS. And the servo directly on the output from the FC board.

What do I see at Config/mandatory hardware/servo output
1 - Aileron, moves when using stick
2 - Elevator, moves when using stick
3 - ESC, does not move when using stick
4 - moves when using stick
5 - Is RCIN5

On FC board a green LED flashes
Working with DATA horizon and GPS.

What’s going wrong:
The servos do nothing.

I’ve been active on google for 2 days now to see what the problem is, but I can’t get any further.
Everything seems to work, horizon, GPS everything. It looks good.

Hopefully you have some advice, after a few days I don’t know what to do anymore. This is my 1st Arduplane project, so no experience in what it could be.

Hello

They are working now.
This is what have done.

I now have three planes with FC board. Two with Omnibus F4V3 and one with MATEK-F405 Wing. All three on INAV.
For ArduPilot I am an absolute beginner. Now let’s see if I can get the wireless telemetry working.
I’ve tried a few more things, and that’s not helpful if you’re testing later. Because now I don’t know what really is the reason for succes.
But, the servo’s are moving now!
Bye
Regards, Frans.
