H very close to the J? hmm. the last I checked, it was more than 500 lbs lighter.
Also, its only 200 lbs heavier than a G while having 200 extra hp. To me, it's like a very nicely turning P-38J, but slightly easier to overheat.
As much as I love MesserSpits, it seems vastly unfair that we have so many models that are similar while not having the P-38H. The Spitfire XVI is very similar to the VIII but with clipped wings. That in itself is a relatively small modification. I mean think about it. If we only had the VIII and someone asked for a clipped wing XVI, many people would yell and whine... but we have it. To say that the H, turning like a G but climbing like a J is too similar to a J to be added, then that seems to make me think that the Spitfire XVI is just too similar to the VIII to have been added.
The F4U as well, though my main ride, is something of the same sort. The F4U-1A climbs and accels like the D, but turns like the 1-hog. It's actually similar in every way to the D-hog but it's just lacking pylons. The similarities are so obvious that the H should justly be added. The A-hog is to the D-hog as the P-38H is to the P-38J... if you get my drift. Or does it need a completely different ordnance load to be considered 'different enough'? If it's a matter of numbers, go perk it. Consider this: The C-hog = a D-hog with 4x 20mm, practically identical in every other way. Yes, the perk ordnance system will replace it, but it's not the end for the C-hog.
As for the 109, we have the G6 which really, doesn't seem very much of an addon. They say it's fun, and I don't disagree, but you'd might as well take a G2.
