The P-51 that is.Which variant was the fastest.I think I heard somewhere that the D had more fuel.So the ponies could go all the way with the heavies?

I think it was the D that was fatest....B and C aren't much different...but both of those probably manuver better than the D.

Surely the D model had more gas capicity?

I thought I remembered reading somewhere that the earlier marks had thinner wings, limiting armament, but potenitially providing for greater speed. However, I also think the engine is stronger in the later marks, which defineately gives greater speed.

An 85 gallon tank was added to the P-51B.

"The last 550 P-51B-5-NAs were fitted with this extra tank, becoming P-51B-7-NAs, and into P-51C-1-NTs, becoming P-51C-3-NT. In addition, some earlier P-51Bs and Cs were modified in the field to accommodate this tank."

This brought (the Modified B's, at least), up to 419 gallons, including external tankage.

What if there were no hypothetical questions?

I'd like to say overall the b/c is my favorite WWII a/c. I'm looking forward to flying it. :)

Yes, every book I own says that the P-51 B/C is faster than the D, but not by more than a couple of knots...the maneuverability was about the same though, just less armament, and yes, less range. And it was Jv44, not Jg44 :)

One less gun/ammo each wing should have increased initial roll rate some, though not sustained roll rate. BTW, I recall some in JG26 removing OTBD guns from their early 190's to improve accelleration/climb/initial roll. Hardcore!!

I read some place (witch I just can't remeber now :-p) that the D model had a slightly supperior top speed over the B/C-model, but because of higher wingloading, it was slightly less maneuverable and often had trouble reaching it's designated top-speed.

The cleaned-and-stripped P-51 K on the other hand, had a far greater top-speed and it was that model that was most succesful in combating the Me 262!
