The Aim axis for Aircraft no longer works, Cannot aim in aircraft using Hold RMB down. No i will not use Camera Zoom as it is a RMB toggle aim which i dislike
you can also zoom by pressing “Y” i think its the default button also check if you have bullet drop enabled (its on the screen you have when you joined into a ARB/AAB battle where you can change your loadout and spawn point etc) and maybe use ammo belts with tracers hope this helps :)
