None of the 190 Normaljager's could turnfight very well that I am aware of except against a few USAAF fighters. There is evidence that the outboard cannon were removed by pilots for pure Air to Air work in order to lighten the 190 and improve the turning circle. They still were not turnfighters even then.
Turnfighting is overrated in Reality. I just read an RAF report on flying a 109G14 were it took the 4.5 seconds at, I think, 250 IAS to roll the plane 360 degrees. It was just a tad worse than the Spitfire. The 190's roll was stable, controllable, and fast. It could roll 360, according to what I have read, anywhere from 1.5 seconds to 2.5 seconds. With the ability to roll, change direction, accellerate quickly, and a good zoom climb the 190 was more than a handfull without having to turn turning.
It was an energy fighter from the day it entered combat. Kurt Tank could have put bigger wings on it. In fact they did. They increased the wing size over the V1 in the V5. The new wing reduced Top Speed by about 10 mph but increased manuverability all around.
