I'm making a F550 based drone using some kit I found on the internet and a pixhawk.
I did all the installation, calibration and RC calibration to achieve this.
I'm using QGroundControl to configure everything but I'm experiencing some problems when arming the drone.
I'm able to arm the Pixhawk through QGroundControl and the RC interface using the Telem1 port and the antenna USB stick as demonstrated on this video: https://www.youtube.com/watch?v=AE5MzUDvLq4
So my next step is trying to do the same without the laptop and using the safety switch.
When I do that, it refuses to arm, as shown in this video: https://www.youtube.com/watch?v=0Q5xHEuhP64
Does anyone know what could be happening?
Thank you in advance.
