Hi jeroll3d,
Try to fly German aircrafts. Try not to turn, try to keep high speed, try to only attack with energy advantage and surprise, try not to attack when you do not have full advantage. See if you find it easy, especially late war scenario.
Then you will notice: turning is useless, duel sucks but being a murderer rocks, speed and big guns are your best friends!
When flying the inferior type, it is better not to engage at all. Blue side pilots do that very often.
MiG3 vs bombers: as with any other fighters, NEVER EVER attack from dead six o' clock. Try high speed diving attacks there where the bomber has less defensive weapons. 90° deflection shooting is your friend. Cut the throttle in the dive and try not to pick too much speed, remember controls can become very heavy in the MiG3.
Otherwise, true....Choppers are not easy target to destroy with an aircraft, when well flown they can make it very hard for the fighter pilot...Fortunately we haven't got any in game
