Does the MiG-29 have the ability to have that lock within visual range think, where it gives u a box and u have to hover over a target to lock? Cus all the gameplay I’m watching doesn’t prove to me it has it, I think it’s called ACM
Go to game Options>Air Battle Settings>Aircraft's HUD color and you can change it to a bunch of colors I wouldn't recommend anything too crazy as you don't want it to be a distraction. :)
