If you fly Fighters especially or even Attack Planes in general, this bloke (Skywalker Games) has provided me with the best advice I've come across, and now I reluctantly share out of a sense of duty.
I'll say his tactics WORK. Especially shaking tails. Since taking on his tactics i can honestly say I haven't been downed in a dogfight, don't mean I've won them all either - I still need to work on my finishing moves and i've let a few get away though I'm getting there. But nobody's shot me down yet with Skywalkers tactics ringing in my head, yes I have been killed diving into the ground once or twice misjudigng the cutback, but that's me.
I think you'll find his stuff very helpful (there's more, check his channel). If you disagree with it feel free to post so and why because I'd like to hear it.
If it works for you hope not to see you on the Battlefield.
