Ah, anither flappy flier!
I got in a dogfight with a tight-turning MiG-17, so I took to using the vertical with my F-8. However, I'd always overshoot when I was coming down on him, and he was pulling 8G turns at 100 knots. I got fed up with chasing him around when he got behind me, so I put out flaps an kept climbing through a vertical scissors manuver while he stalled and dropped. Then I rolled over on my back, put the airbrakes out and stalled right behind him, and whith flaps still out, as he pulled up I cut inside, waited untill the last second and fired a burst of seven (rounds, not seconds). He blew up in my face, and luckily I got through the FOD cloud. I got some good pics, too!
with the F-4 try using the vertical more to knock off those MiGs. Climb up really high, then pull over and dive down on them. Works (almost) every time!
