Hi Wotan,
Carson's article was written to make the Me 109 look bad, at the cost of historical and factual accuracy.
For example, Carson snipes at the Me 109 for its poor drag coefficient in comparison to the Spitfire, neglecting that the total drag is the product of drag coefficient and frontal area - where the Me 109 had the advantage.
Carson advice on how to improve the Me 109 is also quite ignorant. The Me 109's radiator design, which had been revised with the F variant, was highly efficient and acutually a different application of the same principles that made the Mustang's radiator famous.
Carson flew Mustangs and obviously didn't like the Me 109's automatic leading edge slats. Ironically, the experts at North American must have liked them a bit better, as they incorporated them into the F-86 Sabre, the Mustang's jet-driven successor.
There are many more statements that don't survive a closer look.
However, I'd suggest that his assertion
"That gap causes the outboard 15 feet of each wing to be totally turbulent."
must have merely been distorted by a typo, since there'd been little wing left for the 30-ft-wingspan Messerschmitt to create any useful lift with ;-)
