I've very rarly play against ai on single player, the experience i have is mostly from Human F15 payers, who tend to shoot and run taktic.
I basicly have a speed abouth 800-900 and break hard left/right and try and keep a lock on him. One thing you must not do is to break too hard, and start to bleed to much speed. If you bleed of too much , your dead.
One tactic that works against Mad dogging F 15 is avoide their first missile ( not easy ) , and keep lock on them, if you managed that, their sold, because now you got a solid lock on a running F 15, and one move from him, BANG! dead F15 .
