Okay guys, I'm pretty new to all this, now last night I had an odd situation. I was in a P-51D at 20k feet, there was a furball below me to my 9 oclock low, probably at about 10k feet. I dropped my tanks, switched to my guns, and rolled over into a slight dive straight into the furball, which was about 6v8, nme with advantage, including one 262 upping from the field at the time. I hit about 500 on the red dot(True airspeed?) and 460 on IAS. I was at aobut a 4 degree AoA coming down on this furball, I had the target(BF109) in my sights at 400, I squeeze, miss, 200 comes quickly, hit hit hit, wing falls off. Splash 1 and pull up into a Zoom climb. I used my stored energy(Altitude) to trade for speed. Now, I pulled back up, but somehow, even at that speed, a Spit 5 or 9, can't remember which, caught my tail, and somehow he FOLLOWED me up to about a 3,000ft/m climb rate, while he was turn fighting? HOW did he merge on me and keep up with me when he was going *much* slower than me? I started a slow left not to bleed E, I then pulled an immelman, and came down back into the furball with plenty of speed, suddenly I hear the familiar ping ping, the dang spit 5/9 followed me up from a high E high speed dive zoom and boom tactic and pinged me on my way back down, I realize he was a MUCH better pilot, but explain to me what I did wrong here? I used my advantages as good as I could. I'm tryin to learn but it's just so discouraging when I do what I can and it still doesn't work.
