[Murph]

I have found that by resetting the "center view" with my head slightly lowered allows me to center the gun sight pipper in the 109 by leaning to the right ( which is what real-life 109 pilots had to do). The only German aircraft that this does not work with is the ME 262.
Sights in German aircraft were deliberately offset to the right so that the pilot had to aim using his right eye.
