hi rocketred, good question! I will be interested to hear views on the subject.
I am taking a look at a comparison of aircraft cfg files in MAW, because I am not happy about how some Allied aircraft, in AI mode, seem to munch up perfectly good Axis aircraft like the 109_f4. For example, the Martlet seems to be on steroids.
I don't know how the P38 is supposed to fly, but generally I can take out a lot of things with long range sniping using the 20mm nose cannon.
