First shot opportunity on the La7: You could have made it if you'd lined up and pushed the nose aside to have the right lead... Then let the rudder go.. the nose will come back on target for the shot. Alternatively, you can bank (e.g. left) ~45deg and rudder the nose slightly to the right, which would move the cockpit out of the way and give you a clear (except for cockpit bars) sight of both target La7 and gunsight.
30" and on.. You are too close and too lined up (on his six) with the La7. You need to put yourself in more deflective position for the easy shot, and to avoid overshooting him (with your plane, not the guns), which you almost did.
40" Good shot opportunity, almost as it should be done. Bit more anticipating would have been nearly perfect.
48" An easier way to make this shot would have been wings level. You added some lateral deflection here that's not needed and makes the shot more difficult. It also puts your guns out of plane with the target, which makes it more likely your bullet stream flies around despite the gunsight being aimed correctly.
1'23" Almost overshot.. Still just a tad too close.. And you're getting near to too little E with this plane setup: La7 vs P47 will leave your P47 dead in the water when you're on the deck and out of speed, and co-e. By 1'25" you're saddled point blank but don't have your flaps out for what's nearly a stall fight where you need to pull some lead and take the killshot before the La7 leaves you in the dust with its superior agility and acceleration. Or...
1'43" go up for a quick yoyo to reset the shot setup, but because you commited to saddling up so close, you're barely flying after looping over him and miss the shot as he flat turns in front of you.
1'52" You shouldn't be throttling back on the way up that maneuver. Not in these circumstances.. Unless you're very sure you can spare the advantage.
2'01" Need to work your gunnery a bit
Setup is good, better gunnery is all your missing. Using the rudder to make your snapshot burst rake the target for a bit longer (2-3x as long if you do it right), and/or maybe with a bit of bank so that the elevators can help too, would be perfect.
---
2'23" You made an evasive, that's good, but it was predictable. You should (esp. in this situation: high speed, higher pony bouncing, and you in a low&slow 47) roll into some sort of non-linear (from the attacker's pov) evasive, e.g. that same flat turn and then an upward bend just as he's going to shoot. It would have thrown off that La7 coming for a HO, too.
2'30" Good counter-attack.
2'34" Another shot but you can't really afford so many corrections and repeats like this, it drains your E which is not what a 47 can really afford.
3'00 There's a spit coming, gotta work your SA a bit. It's coming straight at you from 3K out, plenty of time to spot it.
3'21 I would have reversed for the spit asap. You're delaying the engagement while not gaining anything, whereas he's still in a shallow dive: he keeps his position advantage and gains even more speed... Then again you could drag to that friendly as you did, using him as bait. But you have to make it count, otherwise you make the odds even worse for yourself once the friendly dies from the extra con you brought to him. As the spit and 51 were going for the friendly, you could have spliced your trajectory into theirs, bringing you into a dead-6ish position on both of them.
4' Gotta work the gunnery.. That spit should be dead three times over.
4'03 Don't worry about the 51 so much. The spit is a better maneuvering plane and you're very slow. This is your opportunity to pre-empt his evasive by cutting angles into his turn as soon as you recognize it, and finish him off with a good burst. He's already taken a lot of hits, so you wouldn't need much more.
4'12" Yikes.. now you're in a 3:1.. That P51 could have died in the HO if you'd slightly ruddered your guns to him. The Spit16 should generaly be the prime target here, it's the best stall fighter and is already very soft.
4'23" That P51 gives you an easy shot.. Again, gunnery needs work. You could have at least given him good damage. Take the shot but don't linger like that.. The spit16 is still on your case.
4'49 Lots of things could have happened/been done differently since 4'23", can't really get into all of em. At 4'49" you get a great shot opportunity and a good sight of what not to do in the spit's position.. he just scissors right into your guns...
4'52 You give up the shot on the spit to evade the pony right on your six... At this point, given that the pony is obviously not excellent gunner, you could have probably just twisted around into an angle for the shot on the spit16 (not stickstirring, that wastes E) and gotten a shot on the 51 as it overshoots...
5'03 but you pulled some flaps down and didn't immediately nose down to regain some E.. Giving up the spit16 for nothing in exchange.
5'11 The two ponies are coming in for their shot at the same time, and the spit isn't that far out of sync either.. It's a great test of your timing an evasive.. Those flaps should be coming down and you should be nosing down for speed.
5'29" Opportunity for a shot, but you nosed down too much. In this situation you should keep the spit in sight and be anticipating his trajectory so that you can have your guns pointed at him, where he'll fly across you, ahead of time.
5'34" You reverse to the left. It makes it a harder shot for the 51, but you give up what could have been a lead shot on the spit as you both flat turned.
Your flaps are still keeping you slow, and you aren't using all the altitude at your disposal. This would have allowed you to turn quicker or come out of the turn with more speed, or both.
5'57 You're trying to out turn the spit at such low speeds and without an energy advantage, and keeping it fairly flat (even if on a shallow climb, which could work out if you really exploited the flaps to the max). You could have hit the brakes at 5'51", either going up to make the spit overshoot, or down to start a vertical scissor to match the spit's horizontal ones, and gotten an opportunity to saddle up on the spit.
6'10" A good opportunity to stick it to the pony passing by, but that spit's still right on your tail. Big gamble.
6'12" This upward evasive (ish) can't work. You're too slow and at the wrong angle to really move out of his sights. He can just match your maneuver, with his plane and speed. A better alternative would have been to nose down for some speed and then pull up to setup a shot on the spit's next bend. Roller-coaster like.
6'27" You could have spliced your trajectory into the second 51's run on BBQ. Lucky for you he didn't try to hit you, you were dead in the water up there. Pigtail waffles it.. he was about to get a lead shot on you...
That's about it.. no time to say more, sorry
