I can easily defeat AI MiGs in the F-86. The only issue is that the MiGs seem to soak up 50 cal rounds like nothing else. I have run out of ammo fighting one MiG. (while using gun sight) It seems like the engine on the MiG can take 25-30 rounds and still run, and to get a reliable kill I have to get in close and aim for the wing roots. The Sabre seems to be far better then the MiG in the flight characteristics department, so I think you might just need a little practice. Maybe try fighting MiGs with the AI set to novice, until you can learn how the jet handles, and how to best exploit weaknesses in the MiG. I find that the Sabre turns better then the MiG at higher speeds, and it seems to accelerate quicker. Try not to loose too much speed in a turn fight, because the MiG can more easily get on you six if both of you are near stall. I haven't played this jet much though, so I recommend you try to reach your own conclusions. The other thing to note is that the missiles are worthless in a dog fight, and they weigh you down massively. Only use them to hunt bombers, and if you do get into a fight with a MiG, use the Safe Fire button to get rid of them.:D
