F4u1c and F4u1d. Haven't seen this addressed yet.

Don't want a debate here. Can Verm or Pyro answer this.

The F4U-1C had the PW 2800 R-2800-8 DW rated at 2,000 HP maximum for takeoff. Speed on the F4U1A was rated at about 417mph maximum.

The F4U-1D had the PW 2800-8W DW rated at 2,230 HP maximum for with water injection for takeoff. Speed on the 1D was rated at 425mph maximum.

Two different engines with varying horsepower. How is it that the charts on HTC webpage say that performance is the same for both models?

Oh forgot. The F4U-1A and 1C were comparable in performance according to The Great Book Of World War II Airplanes. This is where the numbers come from.

F4U-1A/1C/1D were all equipped with the R-2800-8W engine (Pg. 511 in America's Hundred Thousand).  F4U-1s were built with the R-2800-8 engine although I believe that it was common for them to be retrofitted with WEP (which upgraded their engines to R-2800-8W).

Wep is uber.......

[fscott]

Ok Hooligan that explains it then. HT is modelling the 1C with wep added. Just a correction though, the 1a-1c had the 2800-8 engine and the 1d had the 2800-8W engine. Obviously the W stood for wep.

I know you don't want to get into an argument but....  

"America's Hundred Thousand" is the bible on US fighters.  It says late model 1s (i.e. 1As) and 1Cs were built with the 8W.

To confuse the issue a bit more, in an earlier thread (I believe) Pyro stated that it wasn't clear if the 1C was a variation on the 1A or 1D.  Something about the serial numbers of the 1Cs...

And W is for "Water Injection"

Hooligan

[Fishu]

Ohhh.. another uber point for F4u-1c  

[Vermillion]

Hooligan is right, the only difference in the two engines were the water injection systems.

And only the early -1's lacked the injection systems, but were often refitted.

But -1A's, -1C's, -1D's all were fitted with the same engine.

Hooligan is correct.

[F4UDOA]

Gents,

In fact there really is no such thing as a F4U-1A from a production point of view. The distinction of the the F4U-1A comes from a number of retro fits, the primary one being water injection. The others include a bubble canopy, raised pilot seat, leading edge spoiler on port wing to correct asymetric stalls, debounced landing gear, raised tail wheel and strengthened tail hook.

The first production bird to incorperate all of those features with an official designation was the F4U-1D. It doesn't mean that the F4U-1's didn't come off the assembly line that way, it just means that they were still designated F4U-1. The A was a post production designation.

There is also the question of fuel tanks in the wings, which were deleted on the 1D.

From every photo of the F4U-1C I've seen, it has the same hood as the -1D, not the -1A hood. Plus they have rocket rails the same as the -1D. Even if they weren't based on the -1D, they were upgraded to that standard by the time they saw action.

Late 44, early 45 service. Close support jabo in 44, moved over to multi-role attack platform over Okinawa, more CAP worked into the ground pounding schedule.

Yep, most likely upgraded
