Want to get rid of F3 then do so for every plane in the game.
Why?
Do you honestly think that a single rear gunner with limited visibility anwhere except the rear quarter of the plane and high 6 o'clock is the same as, say, a B-24 with a crew of 10 guys looking in all directions?
Why should the IL2 have F3?
Personally, I don't give a crap about score, and I use the IL2 just as much now as before F3 was removed because..... :drum roll:...... I never used F3 to spot GVs.
