film6: bad decisions got you killed. After you killed the F6F, you flew towards a pack of sea planes with only 250mph and 0 alt. All of those planes had the E to catch you - not a good situation against sea planes when in a 109. Your second mistake was continuing to fly towards the gaggle after that first spit in-in'd you. You should have broken into him and forced the fight away from the horde instead of flying straight.
film7: more bad decisions. The first time you flew right towards the cv low and slow with a gaggle coming out of it... inadvisable. You don't need to grab much, 3k is fine if puffy ack bothers you (sure does me..), 4-5k is generally best. When you died the last time, you didn't cut throttle until you were already vertical. By that time, the spit already had a gun solution and it didn't do any good. You should have cut throttle and ruddered a bit before going into the spiral. I would have cut throttle and banked right a little, rudder left the whole time, THEN gone vertical for a bit of a spiral. A spit might kill you anyway, but at least it'll be a bit more difficult of a shot.
I also noticed that you're shooting from too far away, and taking shots that will at best do superficial damage if they hit at all. You were opening up when the range hit 400, which I think can be anything from 500-300.. not sure on that. Regardless, LW guns have piss-poor velocity out that far, particularly on a dead 6 shot, and will only hurt if you hit a LOT (best of luck to you... I'm shooting 18% right now even with thousands of missed bb's used to make people turn, and I can't kill a damn thing with LW cannon from 400 out). 90 degree deflection or maybe a guy on auto-level and you'll do some damage. I usually don't bother shooting unless I can completely take a plane out. Superficial damage (aileron, etc) only makes people run. I'd rather people assume I'm using no tracers and am a lousy shot. Whenever possible, I don't shoot LW guns until the icon hits 200.
film8: Broken record here... bad decisions. You were burning E going for shots that probably won't hit, and definitely won't kill with. By me, the dora isn't worth flying if you're gonna be attacking anything under 450mph. Getting low in a gaggle like that is just silly. Either hope your targets don't break (don't see you) or break too late, or predict which way they'll break. I'd attack in a dora like I do in a 262.. never have someone who's paying attention in my sights when attacking. I guess which way they're going to turn, throttle back a little (stressing little for a dora), and have them offset to the right or left of my canopy for a slow plane, or between my nose and wing for something fast.
As for how you died... you waited until the LA was too close before breaking. For that type of break to work, you either need to be a lot slower, have a plane that turns better, or start it earlier. That's how I generally reverse when I figure the other guy for a noob and don't want to do something fancy, and I try not to start the turn any closer than d800 if the other guy is only a few mph faster. You made the right choice extending that far to avoid being completely ganged, but the good decisions ended there. 190's are hard to keep up with in a flat scissor, so chop your throttle and go nuts, and shoot him up when he overshoots.
edit: I didn't read SOA's post until going over mine, and Hartmann's tactics will work perfectly in a dora. 109's... not so much. With everyone in the MA flying around at full throttle, it isn't practical (or much fun) trying to fly like that - the 109 doesn't fly so well above 450mph
You definitely need to pick your fights better, especially since you fly LW. When you're one of the only people on your team in icon range, and there are 20 reds, you probably don't want to make yourself a target for them. If you want to fly 109's against a gaggle, keep E on them. I like to make half-assed attacks through gaggles at full throttle (and wep when it won't lawndart me) and try to hit something while compressed. However, my goal isn't to kill anything in the dive... it's to get some of the idiots to follow me vertical (if you dive on a big gaggle, there's bound to be at least 1 willing idiot) so I can pop them from safety as they dangle. That'll work in a dora as well, just be careful and don't get too aggressive in your dive.. don't wanna bleed your E and let something outzoom you.
OK, sleep time.
