To get 40 degrees use
C2 B8 32 3F
45 deg:
D8 0F 49 3F
However I believe 35 deg is optimal, it might appear too narrow at first, but you will get used after minutes of playing.

I tried this morning at 30 degrees which also looks good and brings the background nearer still but leaves the default view rather close to the aircraft. I think that with mods to the view.xml file I can alter this and optimise the way it looks.
Other good spin-offs with this is that your wingmen appear closer in formation and in air combat enemy aircraft are a little easier to spot.
