I bought a Holybro X500 kit with Pixhawk4. I assembled all according to the guide Basic Configuration | PX4 User Guide, but the motors do not work. I tested the motors with direct wiring with Radiolink receiver R9DS and they properly run, but when I connect the ESC input to the board PM07 there are not responses.
I verified that all the wire connection are correct, I connected Radiolink R9DS to Pixhawk4 in S.BUS mode.
Moreover also in QGC there are a couple of inconsistencies:
- When try to run the motor test nothing happens, there are no error messages but still the motor not work;
- When the Holybro is armed the QGC reports flying even if the motors are not working.
Thank you for helping.
