As far as i know the la turns better to the right, so you were turning to his favorite direction. When you get in the trouble with the la better take it round left.
As others have mentioned you want the speed at wich you do the most turn degrees per second, which is way faster than you were. I think you should have tried to get up to 150mph, around that.
I am not totally sure but i think the fuel indicator showed 75percent of fuel. Thats pretty heavy for a p38, your better of having 50 percent or less in the tank. Of course cant blow off fuel when engaging, but maybe try to take off with less fuel and see how it lasts.
I see your working a lot for your flying, filming analysing and posting. Try to check your fuel state now and then and see if you could do with less fuel in the fights somehow, check how much fuel you have left when you get shot down and when you land each time. When you get shot down with 50 percent fuel you had 50 percent more than you needed, generally speaking.
Look at 1:21 , i think that is the moment where you do the mistake. You have a fair position there and are pulling behind him, but instead of pulling around in a light climb you roll over. The rolling cost you turnrate and position, i think pulling higher and behind him there would have been good. Shortly after that you try to pull for your snapshot instead of setting up behind him. With the shot you loose some angle and energy.
I am certainly no P38 expert, but i think those two points are intresting, together with the other stuff mentioned.
Now lets take a look at the turning performance from kweassa:
La-7 (0.05)
ShVAK
- 18 seconds (162mph), 207.5m
- 18 seconds (153mph), 196.0m
- 17 seconds (127mph), 153.6m
B-20
- 18 seconds (162mph), 207.5m
- 17 seconds (151mph), 182.7m
- 17 seconds (126mph), 152.4m
P-38L (0.05)
- 21 seconds (184mph), 275.0m
- 19 seconds (169mph), 228.5m
- 19 seconds (119mph), 160.9m
Of course that is theoretical data, but it shows that p38L goes around best at 169 or 119 mph, still 2 secs slower for a full circle than the la7. That means the la7 would go around you in like 10 circles, 170 seconds or close to 3 minutes. You did the circling with it for 4 minutes you did way better than expected by the data.
