Which Blacksheep was he?
I have some speed and climb data from the P-47M manufacturer that I would like to compare with similar data for the F4U-4. (Basically, I'm looking for some performance specs for the F4U-4 Corsair here)
This data is for the P-47M at combat gross weight of 13,275lbs (full fuel and ammo) and WEP.
Top speed @ 5,000ft = 386mph
Top speed @ 15,000ft = 422mph
Top speed @ 32,000ft = 470mph
Climb rate @ 5,000ft = 3,775ft/min
Climb rate @ 15,000ft = 3,425ft/min
Climb rate @ 28,000ft = 2,375ft/min
From JonJGoldberg's data, it looks like the gross weight of the F4U-4 is 12,450lbs. I have to sort of estimate the exact numbers from the chart he provided which I have relocated below so here goes.
Top speed @ 5,000ft = 380mph
Top speed @ 15,000ft = 425mph
Top speed @ 32,000ft = 445mph
Climb rate @ 5,000ft = 3,750ft/min
Climb rate @ 15,000ft = 3,600ft/min
Climb rate @ 28,000ft = 1,800ft/min
