FS2004/FSX Republic P47J experimental fighter:
==============================================
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.
Serial# 43-46952

Installation:
==============

-Unzip "XP47J" into a temporary file and move the "XP47J" folder into the main Aircraft directory.
-Attention...the panel.cfg files are different for FSX and FS2004.
-For FSX,change the FSXpanel.cfg into panel.cfg and let it replace the first one.
For FS2004,change the FS9panel.cfg into panel.cfg and let it replace the first one.

-Read instructions carefully when installing the P47d.gau (you find it in the XP47J\gauges map), say YES...when asked if the gauges sources should be trusted. If you say no....most of the gauges are not going to work !
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
-Leave the "fighter" map in your panel folder.
-Copy the effects into the Microsoft Games\Flight Simulator X\effects folder.
-Copy the effects and the 20can.wave into the Microsoft Games\Flight Simulator X\effects folder.
ATTENTION :
-For FS2004, change the FS9_Wing_Guns.fx into fx_Wing_Guns.fx
-For FSX change the FSX_Wing_Guns.fx into fx_Wing_Guns.fx

Flying the model
================
This plane is a fast flying machine. It needs careful handling, especialy for landing. You'll need a lot of elevator trim to hold altitude.

-CTRL+E opens the canopy
-Spoiler key opens/closes exhaust turbo
-Radiator flaps are opened by the close cowl key.
-WEP power boost to 70+ manifold pressure

TAKE-OFF :if you have manual rudder enabled, apply right rudder and brake when you hit the throttle .
Better apply throttle proportionaly and slowly at first.
1.Parking brake on, start engine, 1/4 flaps
2.Disengage parking brake
3.Hold enough rudder, brake to keep the aircraft straight
4.Take off at about 110 Knots, let speed build up, as the plane at first sinks back to the ground, wheels and flaps up at 130 Knots.
5.Approach at 25% flaps, wheels down at 120 Knots.
6.Over the fence at about 105 knots.
7.Touchdown at 80-85 Knots.
