I have followed the instructions to set up the px4 before flying.
When I went out to test the quadcopter, I saw that the quad is not hovering in its place but is slowly moving to the right side and then I want to place the drone 2 meters above the ground but it is not possible, when I move the joystick to take off I have to move the joystick until it is 50% and then the drone can only take off and when the drone takes off it goes up very fast more than 3 meters, so I move the joystick a little to lower the drone and the drone goes down very fast and sometimes it hits the ground.
I’ve watched a video on YouTube about calibration and it’s seems to be a good option but suddenly before test the drone one of my motors burned… Here is the video
