I didn't time it, but I would guess within a few minutes, which seems perfectly reasonable. You don't just hit your top speed like a brick wall. You have to work to get to it, and you have to be vigilant to keep it. Note that the combat report quoted earlier advises pilots not to get slow. This doesn't mean you can get slow for a bit to tease your Zero opponent and then turn on afterburners to whizz up into low earth orbit again.

I learned quickly that altitude was paramount. Whoever had altitude dictated the terms of the battle, and there was nothing a Zero pilot could do to change that — we had him. The F4U could outperform a Zero in every aspect except slow speed manoeuvrability and slow speed rate of climb. Therefore you avoided getting slow when combating a Zero. It took time but eventually we developed tactics and deployed them very effectively... There were times, however, that I tangled with a Zero at slow speed, one on one. In these instances I considered myself fortunate to survive a battle. Of my 21 victories, 17 were against Zeros, and I lost five aircraft in combat. I was shot down three times and I crashed one that ploughed into the line back at base and wiped out another F4U.
The A6M2-21 has a loaded power to weight ratio of .29 kW/kg while the Corsair has one of .23kW/kg which is a 26% advantage in favor of the Zero. The A6M3 hamp has even better power to weight ratio at .31kW/kg, loaded. Don't expect miracles.

I've flown the Corsair quite a few times in the game, and I have to say that the only thing I don't like about it is that it tends to be a bit of a "wobbly goblin" in the yaw axis. Other than that, I like it.

The machine is more in its element the faster it goes. The faster the better. It rolls better than most at speed, but you have to take it easy in the turns, even at high speed!

I suspect a lot of the complaints stem from how some fly the Corsair, in that they rely too much on applying engine power to give them the speed they need, when in fact you have to fly the plane in a manner that will give you the most speed with the least amount of effort from the plane or pilot. In part, that means long, gentle high speed turns, and not aggressive fighting turns to stay in a fight. If you dive down on a target but the trigonometry of the situation isn't looking good, oh well... Continue on your way while maintaining your high speed (and don't squander it with a hard turn!), use your speed to regain altitude, be patient, and set yourself up for another pass. If someone else snags him in the meantime, tough. Get over it and move on.

Yes, it's a conservative, time-consuming, and - to some - a boring way to fight, but it's efficient and effective. At least it has been for me.

Also, you don't want the props to be at fine pitch during all this. Ideally, 2500 RPM, give or take a hundred or so while gyrating round, is what you want. Higher RPMs does not equal higher speed when you're already moving fast. At high speed, you want a more coarse propeller pitch to bite more air out from front of you to move quickly. The engine generates enough power to provide the torque necessary to do this at the selected RPMs. Also, you lower operating temps with a lower RPM, even with closed cowl flaps.

Again, I'm just speaking from personal experience with flying the Corsairs in the game, and I'm sure some will disagree, but that's fine.

I wouldn't expect it to accelerate like a car... Maybe I am doing something wrong but even with using throttle and pitch it is difficult for me to get any real speed out of the AC and it seems to overheat unless I keep the throttle below 80% or so .. Maybe it is me but a revisit wouldn't hurt by TD even if it was just to spend some time flying it just as a sim pilot to see if theynseenwhat I see.

Who sais, we don't do?
Climb performance and acceleration are directly linked. Is something off with climb performance on the F4U? I don't think so.

Anyway, it would be an interesting test to let a P-47 and F4U doing same maneuvers side by side.

Luno's quote pretty much says it all about fighting the F4U. Note this man had been shot down THREE times. That speaks volumes about the amount of punishment an F4U could take and still keep the pilot alive to fight another day. A Zero pilot would be lucky to survive one shoot down, let alone three.

I took the F4U up last night in game to check all this out for myself. In level flight at 5000m I was able to attain and hold 300 mph. My controls are old and not well centered these days to keeping the slip ball in the middle was difficult at best, I could have gone faster. It does take a little while to attain this speed, but nothing out of what I would call realistic.

After this I took her on a power dive to just above sea level (Solomons 43 map) and screamed along at 430mph until speed bled off, keeping high 300s for a long time. Reminded me of how much of a performing fool the F4U can be when handled with love and care

After some more testing, I did find something funny. It appears that the speed gauge in the cockpit is under-reporting but a very large margin. So, actual indicated airspeed is 350 or so, but it looks like 290 on the gauge.

Maybe I'm reading it wrong though.

If you can, test with the speed-bar on and convert to TAS.

The speed gauge in the F4U is in KNOTS
When flying 350 mph it should read around 300 knots.

Lol, that's a head slapper. Thanks.

I was going to ask the people complaining about the F4U's speed if they're flying with the airbrakes on, but this looks like the more likely (and less sarcastic) reason for their low readings.

I remember thinking "oooo, nice!" the first time I did a high speed turn while tracking a target in the F4U; so smooth. It's the best high-speed turner in the game in my opinion, all the other fast planes are more jumpy and nervous above 350mph.

The low-speed handling is not that bad either; I can definitely out-turn the 190 and even the less experienced 109 pilots, as long as they're in a G6 or later 109. You need to drop down to very low, landing-flap speed quickly and be very careful about detecting the stall; an FFB joystick probably helps here.

Japanese planes are another story, the N1K1 is a monster down low, and the Ki84 and J2M are tough anywhere. The Ki61 is slower and very delicate, and the tactics against the Zero are obvious.

Don't climb at speeds slower than 175mph, it makes a big difference in the climb rate. It does take long to get to its max level speed, but it you climb a bit and then dive to your desired altitude it will retain its speed for a long time.

If there is one similar plane to look at before looking at the F4U, it's definitely the F6F; now there's a slug. For every plane in the game I can think of at least a couple pilots who do well in it (including quite a few in the F4U), except for the Hellcat.

A similar test was made during WWII, flying side by side a Corsair and a Hellcat.
According to Corky Meyer, who was Grumman test pilot in WWII and participated in the test, they showed identical performances. The slower F6F wasn’t slower at all, but have a badly placed static port, that caused lower airspeed readings.

The whole story can be read in the book “Corky Meyer’s Flight Journal”, written by Meyer himself and published by Specialty Press.
