"P38 can climb away from a spitfire mkIX when using wep"
Er.. no. This is the one thing you must NEVER do when having a spit on your 6. The spit will simply level off and wep and catch you. Why? 38 may climb better, but it wont outclimb a hail of 50 cal and 20mm bullets. Spits level and get to d900 of you then they start their own climb, getting to d600 and firing. They wont stay in range for long, but they just level again and repeat till they ping you to death. This outclimbing thing MAY work above 20k, but below, not a fat chance in hell.
This is vs spitIX of course.
"P38 just need enough "performance" to put his nose at up to 1 km of the target."
Partly true. However, the 50 cals dont do any serious damage past d650. I've pinged a con at d900 so many times it seemed to glow. No damage to it. And this is with the "alleged" nose guns in 38 hitting in a tight spot. The only time a 38 guns deal damage at long ranges is when the target is showing its planform to you, aka, a 109g10 zooming up, it gets to d900 from you, 38 about to stall, the 109 begins to flip over to come down, 38 fires a LOT of bullets and hits it and snaps its wing off. If this had been a rear aspect shot, nothing wouldve happened. But since it hit from a "top" view, the wings get sliced off. And even this requires you shoot off at leasy 800 rnds and hit with about 100 or 150 of them.
"With D9 you need enough "performance" to put your nose at up to 400 yards of the target."
With the d9's performance thats extremely easy.
"In the other hand, if you want to flee from a P38 you need enough "performance" to put your plane 1 km away of the P38."
True. However, read the above, you will know not to give your planform. If you dont I can ping your bellybutton all I want and not damage you.
"If you want to flee from a D9, more than 400 yards are enough. Now add guns lethality and snapshot capability to the equation."
But the question is, WHAT planes can actually FLEE from a d9? Only ones I can think of are the tiffie, the g10, the la7 and the pony . And only the tiffie and la7 can actually do it without diving or having to fly relatively level to gain speed.
