First of all, understand the difference in the models.
190A-5: Best turner of the group and probably the lightest. Like the D-9, only two fuel tanks.
190A-8: Best gun package of the group and thus the best buff hunter. An extra fuel tank offers extended range, it's heavily aromored and can really take a beating but is, along with the F-8, the slowest of the group.
190D-9: Among the fastest aircraft in the game. A pure B'n'Z fighter.
190F-8: Performance similar to the A-8, the F-8 is the best ground attack plane of the family. The bomb and the rockets are deadly to GV's. Don't fire the rockets until the GV has just passed out of sight under your nose.
Ta152-H: Among the best high-alt fighters in the game. Very fast over 20K, good gun package and glides forever if the engine quits (It's prone to radiator damage). The 152 is slowest in a dive (you need to keep it in the 450 range where the others are good for 600+).
That said there are many similarities among them:
Keep the 190 fast whenever possible. The common "It can't turn" wisdom is false. You can flat-turn for ~540 degrees before it starts to lose speed and you have to exit. When turning, never turn so hard that the stall buzzer sounds. That said, if you sense the other pilot isn't as good as you, you can dump as many as all three notches of flaps and go for it. The first set will engage at ~175 mph. If you start to lose ground, pull the flaps in, hit WEP to extend, then turn back and re-set the fight. I wouldn't do this until you have quite a bit of experience though. The 190's, particularily the A-8, have a nasty snap-roll when slow that will auger you if you don't feel it coming.
Use the 190's incredible (best of any plane) roll rate to rotate your lift vector for instantaneous changes in direction. The 190's dont climb that well sustained, but are among the best zoom-climbers with a head of steam. Use this, along with your roll rate to fight in the vertical rather than sustained horizontal turns. A zoom climb with a 180 degree roll at the top and a reverse back down will score you a lot of kills (this also works great in the 109K-4 BTW).
Defensively, if you've gotten yourself into trouble and have air under you, a defensive spiral or a straight dive will often get you clear. Not many planes will hang with you at 600 mph. If your stuck on the deck with someone saddled-up, then a flat or rolling scissors are your best bets. Unless the opponent knows what he's doing, you can often force an overshoot or bring it to a nose to nose fight where you can get a high forward deflection.
Good luck. The 190 is an awsome plane once you learn to fly it.
