I never knew that the A8 could outturn a A5. Not that it matters, 190's turn like lumber wagons.
But I have seen discussion that the 190's could deploy flaps for manuevering, at least at round 250mph or some thing like that.
All in all the A8 is an unbelievably deadly machine if flown to it's strengths, which are speed in the dive, massive fire power, good views, and long range. It is a BNZ dream.

I couldn't care less if they changed a thing about the A8, you learn to fly her right just as she is, and she will amaze you.

Fly her wrong, and you are a target. But I suppose you can say that of any plane.
