I think you could add the C47 to the back feilds for the germans, since they did have JU52s still running trash and bellybutton all over france/germany. I also would like to know why there is no P51D? I mean its not really an issue for me since I prefer the Bravo model anyhow, but I think if the germans have the ME109G10 I think its only fair that we have a hot rod too.
The P51D out performs the Bravo above 15K. The P51Bs best fighting alt is between 15-20K. Where is the P51D seems to really come to life at 25K, where is is really fast. The fact that you are taking the C47s away from the axis, means its not going to be possable for a quick fight, unless we take a feild in France, other than that we will have 109G10s climbing out over the channle to fight. They will always have the alt advantage over the B model Mustang. They will also have the speed advantage.
The 109G10s get up to 25K quicker, and they carry more speed up to that alt, than both the B and the D, but the B is very reserved speed wise at 25K. So I say give the allies the D model too. It was there in 1944, it gives the less talented Pony drivers a chance to live after an attack by an alt-monkey in german iron. You could also give the axis the 190D9 to make up for the P51D addition. (I like shooting those down hehe) I think that would be fair.
Just a thought.
As you can see the G10 is faster with its long running WEP than both the B and D model stang, above 22K, it is way faster than the B model at this alt.
