Keep in mind a couple of points:
The P-47N has the same range on 50% fuel that the D models have on 50%. It also has basically the same climb performance as the D-40 when weighted in this way for a fair comparison.
You'll save more weight by taking light ammo than deleting two of your guns. Having 8 .50s is kind of the whole point of the Jug. IMO the heavy ammo load should be taken as well, if you find it too heavy ya know how to get rid of it.

Oh, btw, if you don't take the 365mph N and if you are so interested in maneuverability, then you might as well go with an F4U-1A. Rugged American engine-radial fighter that rolls well, dives well, zooms well, plus is faster down low on MIL than any D is on WEP, mostly climbs better, and turns substantially better. 6 .50s with lots of ammo will get the job done.
Hello,
I have a question for you P-47 experts. I was just wondering what the impact is on performance of a P-47 (say a N model) when it is light:
- 50% Fuel or less.
- No bomb or fuel tanks (or hard points for carrying them).
- Just the 6 x .50 cals with minimum ammo (yeah I know just).
Would this make a noticeable difference in turning and climbing ability?
Thanks,
Slade
