Does anyone have any data on the climb rate of the p47-N? I've found a few things about the M model, and it's rate of climb was very much superior to the p47-N. Here is the data I have dug up, P-47 N Climb (http://www.wwiiaircraftperformance.org/p-47/p47m-n-climb.jpg), it seems to be a bit better than what we have modeled now. I may just be looking at the wrong stats, any help would be appreciated.

P-47N carries over 1000lbs more fuel than the P-47M. P-47M has main and aux just like a standard P-47D-40 does. P-47N has a LOT of fuel in the wings.
You lighten a P-47N by draining the wing tanks and with WEP on it'll start performing more like a P-47M.

P47N with it's extra weight in a wider wingspan fuel tanke (even empty) and other various things that aren't mentioned here add up to a significant amount.
Remember, the M was actually a P-47 D-27 modded to increase pressure on the turbo and with a new engine.

At nearly same weight, 16,300lbs I got it to climb at about 3200fpm right off the deck to few K of alt, before the rate started dropping. But I used .speed command instead of auto climb. IIRC some 10mph less then usual auto climb speed.
Note
Numbers may not be 100% accurate, since I tested a while ago.
Also, this chart is a bit better: http://www.wwiiaircraftperformance.org/p-47/p-47n-republic-wep.jpg

It just so happens that I have climb data on all four P-47s.. Don't fake being surprised.
Our P-47N climbs better than that shown on the chart referenced, especially above 5,000 feet. Note that the weights are within 300 lbs of each other. I plotted the AH2 P-47N, -25 and -40 on the chart for reference.

As Widewing has pointed out before, "N" sans wep has same horsepower as D40. with heap much more weight. Lotsa guys use wep on N climbout, which rather defeats purpose

600 lbs or so more empty weight I think. And N has a larger wing. I think the "problem" with the N is the massive fuel loads it can carry. Remember, the N can fly for the same amount of time on 50% fuel that the D-40 can on 75%. Don't overload it, and there is not much difference on MIL climb D-40/N.

Thank you for the information fellas. <S>

the M was totally different than the N in every way.
it had the same engine, but was propped and tuned different.
the N was designed to be a long haul fly to fight escort with good range, the M was designed, to be a monster.

P-47M = perked
P-63 = Perked
The last 2 perk planes needed to be added to the set. :rock :rock

No.
P63 would not be perked, P47M could go either way.

if we got the 47M and it wasnt perked, the whines would never stop.. a jug that does 400mph below 10k..
-
The 109K does 400 at 5k :lol
Really it's not that fast.

jug turns better, has better high speed handeling, and better firepower at range... so add to that the speed of a K4.. it would be a tad unbalancing
interesting note though, the M never carried ord, it was a pure dog fighter version of the jug.
-
I'll give you high speed handling, but the K4 can turn with the Jug in a slow fight.
-
I really think the M would be a tough call on whether to perk it. But I just don't see it being perked. Can it really match up with a Spit14, F4U-1C, or F4U-4

Im thinking perk due to its MASSIVE performance increase over the other jugs, non-perked it would render the rest obsolete from a fighter standpoint, they would still be useful for attack though considering the M carried no ord.

At lower altitudes the 109K-4 is a major handful for any P-47. However, at the altitudes where the P-47 was engineered to fight (above 25k, up thru 40k) the K-4 is outclassed. For example, in terms of speed, the P-47N can reach 476 mph at 30k. That said, you can count on one finger the number of times a real fight develops at 30k...

P-63 is a low alt monster. Perfect for AHII. If not perked, then give it an ENY of 5.

Oh good GOD man lay off the frickin' P-63! While many were made, only a handful saw real use! Even with the VVS sneaking a few to Berlin they were very unimportant compared to other craft in this game.

You guys want your IAR 81C's, Brewster Buffalos and Mossie bombers, I want my P-63 :D
(Plus, I really just joke around with it now, I doubt we'll see it any time soon, but nothing wrong with hoping) :pray
-
I want a P-47M so bad it makes my teeth hurt, but still, it needs a perk price.
The P-47M compared to the 109K4 has 8 of the easiest shooting guns in the game, visibility, no dive limitations, roll rate, AND the natural popularity of being an American plane. So it would need a light perk, along the lines of the C-Hog.

I remember a event were i encountered a P47 at 23k, that was possibly one of the best fight's i've had. I shot him down but i can easily tell you that the pilot of that P47N knew his plane ( can't remember pilot name, been gone from AH for about 5 months ). The 109 can easily dominate a jug below 20k with the right pilot behind the stick, but if you run into a jug pilot who know's his stuff above 20k, your in for a suprise!
And is it just me, or does the jug's armor really shows at 20k+? I had put about 5 30mm rounds ( confirmed ) into that plane and he didn't go down, seems that the bullets velocity is affected at those altitudes.

Here are some pics of a P-47M at the WWII show this summer in Reading, Pa.

That last one i use as my desktop background. This plane flew in a low alt luftberry over the field, along with 2 corsairs and a P-40. This was the first time i've seen a jug in person and it was impressive to say the least. Given the choice, i would rather have a 47 than a 51 any day. Just don't make me choose between a P-47 and a F6F. :)

True. I have tried to engage that high and after the first pass the other guy always runs in a hard dive.
