Therefore, we decided to replace the Pixhawk. When under manual control the roll and pitch sticks control the angle of the vehicle (attitude) around the respective axes, the yaw stick controls the rate of rotation above the horizontal plane, and the throttle controls altitude/speed. So for the moment I am only using stabilize flight mode. Since manual and stabilize don't control pitch, it's even possible that channel is reversed on both your radio and the servo.

I’m currently building a small hexarotor with custom frame for my thesis. Also the takeoff is not proper as you can see in the video after performing a slight rotation the drone goes forward and takes off . Also if the ROV is tilted, it doesnt go back to the same angle if you drive it around. The pilot should not take off in AltHold until the altitude controller has been tested in flight. Just one notch in stick direction sends the quad shooting into the air or racing toward the ground and there's no hover point. In QGC I choose “Steadydrone QU4D” as it is what is the nearest configuration.
