Hi oldtard,
Yes, you can adjust that view to your preference using any combination of up, down and left, right arrow keys and page up, page down keys. Hold down the 8 key on the numberpad, make the adjustments, then press F10 to save the view.
You can set it and use it on all planes and vehicles and in all gunner or positions independently. You can also use it while in the film viewer. Check out the websites in my signature for more info and have fun!
