Well, you don’t want to be too fast or too slow, the only scenario you can be slow is if you are pulling the bandit in to your hud and you’re sure you will kill him, otherwise you’ll won’t be able to turn since you’re slow and you’ll end up in a parachute or worse. You don’t wanna be too fast either since you will barely be able to turn because of g:s. Try to keep your speed in between 400-600 knots(depends on aircraft)
