Corsair and Hellcat throttle/supercharger settings?

[stugumby]

can someone shed some light on these settings, im trying some missions and im using 75% power 75 pitch radiator 4 and cant get over 300kph at 2000m. Supercharger changes at 9000 feet and 3rd stage at 15000 feet?

If you look at the curves IL2Compare 4.11 gives you get:
F4U 1st stage switch around 2000m, and 2nd around 6000m
F6F 1st stage switch around 1700m, and 2nd around 6000m

Engaging water injection reduces the full throttle altitude of each stage about 1000m -if IL2compare data is correct.

Looks like ppitch 2 low. Are you diving or level flying?

Do you have the "Aircraft Guide.pdf" in your root IL2 directory? (Can't remember if I put it there, or it it got installed there with one of the patches.) If so, all the supercharger settings for the planes are there.

Level flying cruising into a airfield. had to trim after climb a bit but still seems so slow, fw and bf zip along and so do yaks but the corsair and hellcat seems slow. Realizing of course yaks etc are half the weight and a large horsepower difference.

2000m is not a good altitude for both F6F and F4U - as it is close to a charger switch.
horseback did a lot of accelleration testing here:

He tried reduced prop pitch, and with the sole exception of the P-51 at high speed reducing prop pitch never did increase accelleration.

Corsair and Hellcat had relatively low cruise settings because they were designed to travel long distances over water, engage in combat and then return to a tiny island or even tinier (and moving) aircraft carrier with limited navigation aids; the actual pilots' handbooks call for 2250 rpm (approx 77% prop pitch), 33% rads and about 60% throttle for max endurance cruise, which generally works out to 200 knots at medium alts and somewhat faster up high for the Corsair and around 180-190 knots for the F6F in-game.

IMHO, both need a lot of very precise trimming to get maximum performance in-game, and this may rob you of some of your speed if you don't get it exactly right, but in-game neither aircraft seems to perform to expectations until you get into the 95-110% throttle settings and vary your prop pitch between 85-100%, at which point the overheat indicator likes to come on if you try to sustain maximum settings for more than a minute or two.

In practice, the real aircraft (particularly the F6F) were thought a bit sluggish compared to the late generation USAAF fighters, which were designed for higher cruise speeds and had lighter structures(not having to land on carriers), but the F4U and F6F were considerably faster than the Japanese opposition that they most often faced.

Where can I download carrier landing and takeoff missions for F4u corsair and F6F hellcat?

This is so embarrasing in online server, not being able to land effectively sometimes, you feel like youre letting your team down a little bit. (wasting team ACs)


I need to be able to learn carrier landings with these more modern planes (I can do carrier landings with average effectiveness, with only f4f wildcat)
because the landing speeds are somehow much slower it behaves nicely on landing.

What is your fuel load btw? I remember someone mentioned earlier back in the 4.11 days that 75% is absolutely max you need for F4u. If more than that, the flight curve got worsen. Due to the limitation of the map settings, the long range capability of planes like P51 and F4u are absolutely useless. For normal combat mission, I only load 40% into p51. For F4u, I usually load only 50% to 60%. I am, however, not sure about F6F. There maybe an issue with change of fm curve at 100% fuel load for F6F.
