Modifying Motor Tilt Angles on Multi-Rotor Drone

I have a multi-rotor drone and I’ve set up the model and run it on PX4. Now, I need to make some modifications to make the motors tilt at an angle on the arms, and I know this will affect some files. Can anyone tell me how to do that? Thank you.

Nothing will happen. it will only controls the bank angle of the aircraft. So keep the value from 25 deg to 35deg depending on the size… if your vehicle is big, make it as 25deg.
