1st i will only give u the list, than belowit the reason:
1. LA7
2. FW190D9
3. P51
4. F4U-1C/D
5. Spit IX
to 1.: why the LA7 u ask, pretty simple, its average speed up to 15K is probably the highest atm, and its climbs wonderful, it rolls real good (maybe a bit to good, i have read in the froum its as fast as the FW190) and its has a powerful gun array. Even over 15K its still fast enough to be dangerous. IF u wanna run with it noone will get once u managed it to the deck. For the usuall brawls in AH its a perfect match.
2. The D9, speed, climb, dive and roll, do i ahve to say more? Only plane u really have to fear is an LA7 at co-alt or higher. against the other birds u r able to run if u r out of options.
3. P51, it is still fast anmd dangerous, the guns are cool and have a pretty good ammo load. And not to forget its the fighter with the best forward view for deflection shots.
4. Its very close to the P51, fast deadly and can really take a punishment. It has too a good view forward for nice deflection shots.
5. Yeah the Spit, good climb, the Hispanos and the turning make it a real good plane for AH.
