LOL!
Some nice stuff there, Milton.

You must include Duckie in that list as well. He has the XP47H and Nigel has the XP47J responsibilities. Fliger747 had the flight model duties for both very different aircraft. Lots of things coming together now as we put the finishing touches on them.
Ho my god! what a beautiful aircraft!
I swear, it's like looking at and sitting in a real world classic warbird. I would say unbelievable but
considering where it's coming from.. It's not!
I can not wait to jump into that cold cockpit.
It is a fun place to be unless of course you have to paint all those individual parts
It's been an arduous and challenging task at times but rewarding in the end for all of us.Those are looking amazing! It's great to hear there will be bubble canopy versions as well. That's going to give us some great choices for some really interesting repaints.
Yes, just when you think you are done with the modeling thing, someone gets a brilliant idea (Nigel) to add some fun to the pot.
I do have some side views of some great paint possibilities that I will post as well. Thanks Tom; these have been a long time coming as I and Damian Radice started the "J" in 2009. I set them aside to conclude the AT-11 project and did not pick them back up again until last year."RAAAZZZZZ... WHIP"!
Some nice stuff there, Milton.

Duckie and Nigel have done yeomen's duty on these schemes and interiors I assure you. Fliger747 has been working and tweaking the FM's for these two for a long time, so long that Nigel who can't stay idle for long is on his 4th sound set variation for the "J".
Music to my ears.

Last night was an FSX port over testing event starting with the xp47j and finishing with the CRDA Z1007.
After a few minor texture alpha fixes, things are just about perfect, at least on the ground. "Air time" comes after the ground checks
I also got a quick satisfying peek at the XP47H but had to stay focused on the task at hand.

LOL Thanks guys.
I am looking for two XML based gauges: an accelerometer and a turbo RPM gauge. Anyone know if these exist in freeware that may be share-able with permissions?

XP47J Performance
The fastest version of the Thunderbolt was the XP-47J, which was proposed in November 1942 as a lighter-weight version of the Thunderbolt designed to explore the outer limits of the design's basic performance envelope. The XP-47J was fitted with a 2800 hp Pratt and Whitney R-2800-57(C) housed inside a close-fitting cowling and cooled by a fan. The ventral intake for the CH-5 turbosupercharger was separated from the engine cowling and moved aft. The four-bladed propeller was fitted with a large conical-shaped spinner. The wing structure was lightened and the armament was reduced from eight to six 0.50-inch machine guns. The contract was approved on June 18, 1943.
The XP-47J was a completely new airframe and not a conversion of an existing P-47D. The serial number was 43-46952. The XP-47J flew for the first time on November 26, 1943. On August 4, 1944, it attained a speed of 504 mph in level fight, becoming the first propeller-driven fighter to exceed 500 mph. At one time, it was proposed that the J model would be introduced onto the production line, but the advent of the even more advanced XP-72 resulted in plans for the production of the P-47J being abandoned before any more could be completed.
A proposal to adapt the XP-47J to use contrarotating propellers with an R-2800-61 engine was dropped.
Maximum speed of the XP-47J was 507 mph at 34,300 feet, range was 765 miles at 400 mph, 1070 miles at economical cruising speed. An altitude of 15,000 feet could be reached in 4.5 minutes. Service ceiling was 45,000 feet. Weights were 9663 pounds empty, 12,400 pounds normal loaded, 16,780 pounds maximum. Wingspan was 40 feet 11 inches, length was 33 feet 3 inches, height was 14 feet 2 inches, and wing area was 300 square feet.
------------------------------ More -----------------------------------
The "J" was fitted with a high output version of the P&W R-2800. Specifically, the R-2800-57. This engine made 2,800 hp @ 2,800 rpm at 35,000 feet. This is in War Emergency Power.
The aircraft actually attained 507 mph at an altitude of 34,300 feet. 2,800 hp is 133% of rated power. At military power (100%), the XP-47J could sustain 470 mph. 435 mph was attained at 81% of its rated power (1,700 hp). All performance figures were obtained at 34,300 feet.
The "J" model was an especially good climbing fighter too. It had a climb rate at sea level of 4,900 fpm. At 20,000 feet, it was still rocketing up at 4,400 fpm, and got there in 4 minutes, 15 seconds. Time to 30,000 feet was only 6 minutes, 45 seconds. Now that's an interceptor! Yet it had a usable range of 1,075 miles. Rather impressive, don't you think? No, this was not a stripped down hotrod. It was fully armed and carried ballast in the wings equal to 267 rds per gun. The aircraft was flown to a height of 46,500 feet and was capable of a bit more.

Impressive report Milton. The XP-47J was indeed a real powerhouse of a plane.
Interesting to note that XP-47J was faster and more agile than it's successor, the XP-72 Superbolt. Suffice to say both versions of the "venerable ol' Jug" fell victim to the jet age.

Yes, the "J" was faster than the "H" as well by about 10 knots but the Chrysler GE TSC wasn't fully tweaked in time for testing either. We will likely bring in the "H" at 490 MPH ground speed at altitude and the "J" around 500 MPG GS. Fliger747 has a great job tweaking the performance on both these race horses.

The XP-72 Superbolt used the P&W Major Wasp Engine.... So the P-47-H should be pretty close to the Superbolt's performance envelope. Note the rate of climb numbers on the Superbolt:

Range: 1,200 miles (1,932 km)
Service ceiling: 42,000 ft (12,805 m)
Rate of climb: 5,280 ft/min (26.8 m/s)
