Some planes have gunsights real small, and on these planes, the general problem seems to be the distance between the pilot's head position and the gun sight. On these sort of planes (especially something like the Yak-9U), when you have a historic sight, using the gun zoom isn't enough, u have to manually push the upward arrow key to get it zoomed up to your taste.
The suggestion?
Please let it be possible so you can set and adjust the zoom levels independantly from the "move head forward" arrow key. I know you can always zoom in, press the upward arrow key, and press F10 to save the head position. The problem is, when u save it at this position, when you return to normal field of view, the "normal" state is also affected by the previous head movement.
Please make it possible so that u can zoom the absolute maximum on the gun zoom if you wish, but can retain the "normal" field of view when u leave zoom status.
