Servo is not working when connected to Navio board

After making sure the servo rail is supplied power by a voltage regulator my servo’s still not working. It makes some moves when powering on the system but no reaction to the controller.
If I connect that servo directly to the X8R transmitter (same channel) it does work.
What am I doing wrong?

Have you armed your Navio? By default if you do not arm the board it does not send any signals out to the PWM outputs.

Yes, I have.
Is that normal when arming it and leaving the controller untouched, it gets disarmed after few seconds? If I for example throttle then it doesn’t get disarmed.

Yes that is normal, as it’s a safety feature so you don’t forget it’s armed accidentally :slight_smile:
