The best tip I have is to learn about the energy egg principle and how to use the lift vector to point your plane where you want to go to.
This applies to every fighter regardless of type. Nothing fancy just apply BFM.
The energy egg is rather simple look at an egg,put the fat bottom down and that is how a plane turns in the vertical,you can use the pitch back,which is a nose up reversal to tighten the turn radious.You don’t have to turn straight up but can pitch up at an angle as eaglet suggests.
Turning down hill will increase speed but also increase turn radious, this also called a slice back!
I’d also suggest you work on the barrel roll defence,a hard break turn then a barrel roll to keep the lift vector on the enemy can be very effective, it often forces an overshoot and can put you into a position for a killing shot.
YMMV.
