Fps Arm moves fase

I’m makeing a fps I’v been looking at the fps example, but I attached the arm with gun model to my main camera but when I move the camera up and down the arm moves up and down 100000 times faster, how do I make the arm move with the main camera evenly?

If you remove the camera from your other object and just attach the gun and arm to the camera it should work

remove any motion controlling script of the arm and gun just have it on the camera, then make the arm a child of the camera and it will move ever the camera moves.
