I always used to think rollrates of AH planes modeled quite correctly (at least to my limitted knowledge).
Still have one comment to make, about p38. Hope, it will be useful.
From "America's 100 thousands", by Francis H. Dean, page 160
"The p38 was a large heavy fighter not suited for quick snap or slam-bang maneuvers, and had a particularly slow initila responce in roll due to a high laterl inertial characteristic. The problem was a slow start into a rolland thus an inability to switch quickly form one attitude to another, as in reversino from a turn in one direction to one in the other. As one pilot said "It was disconcerting to havve a fighter barreling in on you, crank the wheel over hard, and just have p-38 sit there. Then, after it slowly rolled the first five or ten degrees of bank it would turn quickly, but the hesitation was sweat-producing. Many combat losses, particularly in North Africa, were attributed to this creaky initial rate of roll. Another pilot noted "The first ten degrees of bank came very slow". Power boosted ailerons, introduced the same time as dive recover flaps, gave the p-38 pilot a lot more "muscle" to improve roll characteristics at high speeds, but did nothing to improve them at low or moderate speeds where maximum roll performance was dependent only on full aileron deflection instead of pilot effort."
I noticed a small inertial in p-38 roll in AH, but it is not large enough to make much difference in fight. What described here shall be more noticable.
