Lol
your complaining about ai gunnery not being realistic
tell me what part of
your aircraft's guns are realistic your using to try shoot them down ?
No overheating no jamming no freezing etc etc etc.................
The ai gunnery is what it is, learn how to attack bombers with the games limitations.
I prefer the head on attack, or across the wings high speed pass using a technique with the gunsight to extreme left or right of the screen to make it impossible for me to attack from the rear quarters, leaving the sight in these positions stops you getting in behind the bombers forcing you to attack at an angle from the side, sounds strange but it works.
