Bald: I have made it extremely clear in every post on this thread that I know there are many very skilled Pony sticks, for whom I have the utmost respect, so what are you trying to tell me exactly?
The 109G is a 7000 lb aircraft. The P51 is a, IIRC 10,000 to 12,000 pound aircraft.
Um, number 1, there is a thing called wing-loading. That is why a ~12,000 lb aircraft called the F4U out-turns a ~9,000 lb aircraft called the Fw-190. Of course you know this. Number 2, a clean pony with full intenal fuel weighs a little bit over 10,000 lbs, according to the AHII E6B. You'd need ordinance to hit 12,000 lbs I think. That is with a full auxilliary tank, and standard procedure was to drain that tank first, before the drops. A Pony with the rear tank mostly drained (probably the heaviest condition one would normally fight in) weighs about 9,750 lbs. Doubtless, you know this as well. A P-51D has a wing area of 235 square feet. This yields a wingloading of 41.5 lbs/ft at that weight. A 109G6 (the most produced 109) weighs 6,806 lbs with a 75% fuel loading, and has a wing area of 173 square feet, yielding a wing-loading of 39.3 lbs/ft. A slight, not massive advantage to the 109. Notice I am being VERY generous to the 109 here by comparing them both at 75%, making the Mustang's greater fuel capacity a disadvantage. As a matter of fact, the Mustang can potentially outrange a 109 w/full internal with just 50% fuel.
And what do we make of the Jug-Mustang and Mustang-190 comparison? Both planes have a notably higher-wingloading, the Jug for is also inferior in power-loading, yet both will turn a smaller circle than the P-51. How do we explain this one away?
