With a high aspect ratio wing, extremely efficient Fowler flaps, and two 1700 horsepower engines with two props to put that power into the air, the P-38 should be able to hang on its props for a long time. Check the power to weight ratio, the wing loading, and then add to it that you have two props, not one, putting that power into the air, while you're at it, consider that the P-38 also has zero net torque. In the hands of a good pilot (better than I), it is and should be lethal if you get low and slow with it and you are not flying a Zeke, or something of that ilk.
If you are going to use historic data to judge the P-38, remember that ONLY the 8th AF had issues with the P-38. Every other group that used the P-38 used it with great success.
For all intents and purposes, the 8th AF (the staff not the men who flew the missions) screwed the pooch on damned near everything they did for most of the war.
