Depending on the speed, the 190A-5 can out turn almost any plane in the game. Its just a matter of getting the other plane either too fast, or too slow.
Our 190A5 is, if I understand correctly, based off of a captured 190G-3. I'm not an expert on the 190's in general, and I know next to nothing about the later models, but, again if I understand it correctly, the result is that we have a 190A5 that is underpowered (they were limited to 1.45 ata at sea level, where ours is limited to 1.36 I think).
Regardless, the 190 is not a turn fighter. 190's have top of the line climb rate, acceleration, and roll. This suits them to BnZ fighting, since they can claw back energy, even if they lose some pulling out or during manuvering, and the roll is great for possitioning the nose during an attack.
