Gotta be a bit tough to slow down in an 86 enough to hang with that Peashooter :)

Even scarier to think that some Peashooters went up in the Philippines alongside those early P40s against the Japanese

Test pilots described the Tigercat as "two Bearcats strapped together."

They did see service in WWII. At least the night fighter version did. Two Marine F7F-2Ns flew a single night time patrol from Okinawa the day before the surrender, but did not encounter any Japanese aircraft.

The Navy's chief test pilot called the F7F, "the best fighter I ever flew", and he flew them all. He wasn't thrilled with the poor rearward vision, and the rudder was too small to fly it on one engine without extreme leg fatigue. That said, it's combination of speed, climb, range and firepower were unequaled in a carrier fighter. Published climb data is for MIL power, not WEP. Around 4,500 fpm in MIL power, jumping to nearly 6,000 fpm in WEP with 375 gallons of fuel at takeoff. About 380 mph at sea level for the F7F-1 using WEP. It was, and still is, a monster.

The ship carrying the crew for VMF(N)-533 were enroute to Guam when the atomic bomb was dropped - they Flew via Iwo Jima to Okinawa arriving the day before the end of World war two.
It wasn't in squadron strength yet, and the crews haven't even flown one mission.

If HTC decided, then the F7F-2N's would be the one added in game.
Top speed of 403 MPH sealevel, 445 at 20,000ft. Max Ceiling was 40,600ft and range of 1790 miles on internal fuel, and a climb rate of 5,200 FPM.

If It did get added, HOLY perk mobile..... (as a joke I think all of the P38 Lightening crew would change that lightening in a bottle to Tigercats)

Hmm...I don't recall seeing any documentation giving 6000fpm climb rate.

Here's published figures for War Emergency Power: http://www.wwiiaircraftperformance.org/f7f/F7F-1_Airplane_Characteristics_Performance.pdf (http://www.wwiiaircraftperformance.org/f7f/F7F-1_Airplane_Characteristics_Performance.pdf)

They list 4360fpm with 426 gallons of fuel onboard.

I doubt a 51 gallon decrease in fuel load would produce 1640fpm increase in climbrate.

That figure is for the XF7F-1. Further down in the document is the climb chart for the F7F-1, which attained 4,250 fpm in MIL power (the production aircraft had a newer, high activity prop). In October 1945, the Navy did a test with an F7F-3. From a standing start, the aircraft reached 10,000 feet in 104 seconds. That's an average of 5,769 fpm, including the takeoff roll. An F8F-1 was also tested the same way (in 1946). From a standing start, it reached 10,000 ft in 96 seconds. This record stood unbeaten until Rare Bear edged it out (91.9 seconds, IIRC). That's averaging 6,250 fpm (including the takeoff roll). Like the F7F-3, this was an unmodified F8F-1, carrying ballast equal to the weight of MG ammo.

If the document would list XF7F-1 figures, shouldn't it read XF7F-1 instead of F7F-1?

Actually it lists the different weight configs/powersettings as 1-8 in the tables, "1" being the War Emergency rating/full internal fuel. In the climb chart it lists the only climb curve exceeding 4000fpm as "1". Also, looking at the chart it indicates 4360fpm, not 4250fpm which indeed was the listed climb rate of the XF7F-1. I think it is very clearly meaning WEP-rating for the highest climb rate.

Yep, that doc lists an F7F-1 (No.80262) having an inital climb rate of 4250fpm at military power. WEP increases the total power output by ~600hp.

I must say that, without any documentation regarding the time-to-climb test to 10000ft, I just can't see 1750fpm increase climb rate obtainable with a power increase from 4200hp to 4800hp.

At WEP this F7F-1 would have a power loading of 4.46lbs/hp which is slightly better than Spitfire Mk.XIV at 18lbs power setting for example (4.60lbs). When Spitfire manages an 4700fpm initial climb rate, 6000fpm from F7F-1 is very very hard to believe without any detailed documentation. The prop effiency and the contours behind the prop obviously have a great deal of effect here but the difference is so huge. I haven't been able to find any proper documention for this experiment, I'd really be interested in reading about it further.

I think that the missing item is the Navy's change-over to AN-F-33 115/145 octane fuel. It was required for the C series R-2800s to reach maximum combat boost safely, and beginning in late April of 1945, 115/145 entered the fleet distribution system. Those aircraft requiring it included the F4U-4, F8F-1 and the two F7F versions in service. The F8F and F7F that set the climb records were doing so with the 115/145 fuel and at least 72" of MAP.
