Well indeed, pellik has a point.
The long-range sniping aspect of games like Aces High makes a lot of things twisted and hard as compared to real life.
According to sources like Anthony Williams, 200 meters is about the absolute limit of A2A gunnery against another fighter. 400 meters is the limit against a large, slow, non-maneuvering bomber.
It's not about the ballistics, but rather the situational complexity concerning A2A gunnery which makes targetting over certain distances ultimately futile. Sakai taunts the USN pilots in his Biography, saying "over 500 meters, they are doing nothing but wasting ammunition".
Ofcourse, this doesn't apply to just the P-38, but all the planes in the game.
Whereas in real life, a 300 yard separation would be enough "zoom distance" to execute a nice rope-a-dope, in AH2 you would need at least more than 600 to be safe, especially against Hispano or 50cal armed planes or 109s/La-7s with centerline armament.
The Spit14 is quite a bit more powerful than the P-38J or L in many ways in AH, and in many occasions it wouldn't have much problem outzooming a P-38 in the vertical by 300~400 yards. But of course, this separation just isn't enough.
It's the same thing with all planes that are known to 'zoom like the helicopter'.
The 190A-5 vs Spit5 match up.. 109F-4 vs Spit5 match up.... Ki-84 vs F4U-1D match up.. etc etc...
The 190, 109, F4U are all faster and can outzoom the Spit5 and the Ki-84.. but just not enough to be safe. Inside 400 yards, practically dead.
Just for the sake of discussion, let's assume for some reason the bullets just don't hit outside of 200 yards in the game. If things are ever like this, the Spit14 has plenty enough juice to outzoom P-38s - at least, enough to be safe and execute a reversal.
...
Looking back on how it used to be in AH1 where long range sniping was even worse.. AH2 is still an improvement.
However, if a Spit14 or a Bf109G-10 has to engage a P-38 of simular pilot skill as oneself, starting out from co-E, then the only real safe way to gain a decisive edge is to take the fight long and slow.
Lots of climbs, long and boring extensions.. etc etc... until the pure vertical separation between the two aircraft is large enough to give the Spit14 a one-sided BnZ opportunity, using the speed and climb advantage to the fullest.
A temporary, small margin of speed advantage just isn't enough to rope a P-38. At least, not in AH.
