I’m sorry if its the wrong tag and everything im trying to get to know that better but on the plane DB-LK.
I was doing test driving new vehicles and I tested the plane beacuase I wanted to consider buying it, but then I saw that the machine guns are modeled and even you can choose what ammo you can have but they just don’t give you an option to shoot nor they appear on top left. Hope you have a nice day.
Switch your view to gunner view.
They are controlled by gunner, not by pilot.
