Well my friends, spit9 is the issue.
In relation to the late war monsters in AH, the Spit9 is too slow to be perked.
The Spit 9 was a fast plane, yet in AH it is one of the slowest. Not such a great accelerating plane either, and not a good diver. Actually I have been wondering whether it is UNDERMODELLED!
And if some of you think it is too uber in turning and stall characterisitcs, well, then that would be correct modelling, because the spit truly was an uber turner and had a very gentle stall.
But to perk it, nana.
The Spit9 however has, if my memory serves me, some model errors, but minimal. Something about subvariants, I think. Which brings in anopther issue, how about the clipped wing variant?
The spit14 however is another different concern. That thing accelerates, climbs, runs, shoots and turns incredibly. Nothing that can turn with it, can either climb or run with it, and nothing that fast is that maneuverable. Although the brits made the 14 by the hundreds, it would have to be lightly perked in AH, otherwise there would just be endless scores of this plane in the skies
