NP. But I wouldn't quite call him a liar. Maybe a smart ass is more appropriate. Like I said, if the carrier is going full tilt (30+ knots)...a little more than half a carrier you should be able to do it according to the chart. So maybe he did that.

Thanks for the advice, I edited it.

Full tilt is doable but not without dipping below the deck. Like I posted before, top speed of the carriers at the time was 33.25 knots. I'm curious if he fudged that a bit.

I wish you guys would focus on something else but take off, it is a bit longer than it should be and it was said it is going to be changed a.s.a.p. So if that is your only worry, you don't need to worry any more at all.

How about an answer to this one:

How is this achieved? Altitude, throttle, pitch, fuel, armament, difficulty switches (overheating on/off)? I have never been able to get this out of a Corsair in this sim in level flight with full real settings or otherwise. Please give me a scenario and I will try to duplicate it.

I achieved 660 km/h full switch minus
- unlimited fuel in order to keep conditions constant
- cockpit off so I could see the speed
- no wind and turbulence as this adds a random element
in a F4U-1D, standard loadout, 100% fuel at 20000ft on the Crimea map, noon, all out, rads closed, 3rd gear charger.

I could maintain that for a while before the engine gave in. 660 km/h is 410 mph.

I'll give that a try. One thing I'm wondering is what you mean by "the engine gave in". How long did this take? The corsair was able to travel fairly decent distances at this speed without a problem. This is taken from Wikipedia:

"On 1 October, the XF4U-1 became the first single-engine U.S. fighter to fly faster than 400 mph (640 km/h) by setting an average ground speed of 405 miles per hour (652 km/h) during a flight from Stratford to Hartford."

That's over 50 miles from wheels up to wheels down. That is a pretty sustained distance and I'm sure they weren't blowing their engine to do it.

Okay, I stand corrected on the atmospheric temperature but it also says the top speed was 431mph... should we dwell on that now as well? Besides you already dismissed the data in question when you made the little red arrows pointing to the fact that the aircraft used in that test was "the cleaned up version". And as I have pointed out twice since then:

This test was done early in 1943 on the earlier 1942 F4U-1s. After which the improvements were made and the C and D models were produced. Once again, refer to THIS document for the relevant test results on the 1944, 1945 C and D models we use in the sim.


What I want to know is why are you trying to nit-pick at every little thing you can find simply to dismiss the facts when YOU KNOW the F4U in the game have nowhere near the capability they should. The real world data is in front of you, please just fix the mistake.

XF4U-1 is hardly a battle ready aircraft with wepons and all the imperfections of mass series production. Record setting aircraft are usually stripped of all unecessary equipment, perfectly maintained and aerodynamically cleanedw, which is hardly the case of combat aircraft that never achieve factory data and hardly so data of some record setting aircraft. I wonder what the result would be with a corsair having flown 5 missions in PTO loaded with guns, amno and maintained in the field.

Excellent news! That will make a lot of carrier jocks happy!

That's a start but the issue of the decreased speed of the aircraft still needs to be and addressed.
