My advice is
DON'T FLY THEM!!!. It pains me very time I shoot one down. Less 190s in the air, less guilty I feel at the end of the night.
As for real advice, use the rudder to turn. While in most planes a simple turn involves rolling 45-90 degrees and pulling back on the stick while using rudder and ailerons to keep nose in position, the 190 is just the opposite. Roll only 45-60 degrees, hard rudder into the turn and use elevators and ailerons to keep nose steady. This takes a lot of practice for some, but yields the best results.
As for the knocks on the 190, while most of the world was still mired in the slow agile plane concept of the old Bi-planes, the 190 marked a new direction for combat airplanes. Power, speed and enough agility to get out of a turn as fast as you got into one.
We (and I use that term loosely) engage in insane turn fights because we can. There is no fear of death, injury or even damaging our plane. The 190 was specifically designed to get a 1-3 second gun solution and then be able to "reset" if terminal damage was not inflicted. To the AH community, simply put, BnZ. It's wasn't designed to follow some **** through 85 ACMs, down 12,000 ft. only to wind up otd to get picked by someone else.
