I think, more than anything, it's an issue with the spit modeling.
I was in a Ta152, had speed and alt at about 8-10k. A spixteen zooms up from below me with a bit of speed so I spiral climb up. It takes him a while to stall out, but when he does (at 600 yards) he stalls hard enough to dip a wing. I was saving my E for this, so I'm about to roll in on him and he recovers.
From a stalled out position he recovers, noses UP at me in an 80-degree climb, and stays laser-aimed at me (never rolling, faltering, spinning, dipping a wing) while I use all the rest of my E spiralling way way higher to get away (and he stays with me, 600-800, perfectly aligned with his target), but the spixteen that had just stalled out hard was able to catch a faster, higher E-state, ta152.
This was just last night. A squaddie zoomed in at the last second and killed said spitty, I think. It was a busy night, I can't recall. Regardless, the spit model is bogus. It's more like flying TIE Fighter (Lucasarts) than a spitfire in this game.
