I have never flew the real mustang, but my grand father did. In his journal he talked about the diffrence between a few planes. His squadron first started out in P40, then went to the P51 B models, then they got some new C models and then the D. The D model was tolerated but not well liked. Alot of pilots, stayed in Bs and Cs, not becuase there wernt enough Ds, but because they liked the B and Cs better.
As for AH I think they have the FM just about right on the Pony D and B, well as close as they can get it. Since I have started flying the P51 B, I have noticed how much easer it is to get kills in. So long as I stay up high, and keep my E. The ONLY down sides, are the visabilty, and the guns. It only has four .50s, and it only carries 2 500lb bombs. The rocket tubes are pretty light, and when the rockets are used up, you can still fight pretty good with them on. The rocket tubes seem to make the rockets really go where you want them.
Over all I think the P51B is one of the best planes in the game. I would love to see it with a malcolm hood. I would love to see AH2 with a P51C model too. That would give us the same performance as the B model, with out the rocket tubes, and loading 2 1,000Lbers on it. Still only 4 .50s but hey.... works for me.
