AI Corsair, your worst best friends.

[Gunfreak]

In a 12 v 12 fight with corsair and 109s all set to ace. I've run through this mission 8 times now. 

1 time i was shot down by 109.

In 4 fights i got hit but only lightly.

In the 7 times i surived. The AI corsairs just murdered the 109s. I'm fighting as hard as I can slowly working my way closer and closer to a 109. Then then some AI dick just comes in from nowhere and kills my guy. This happened 7 times. 

In all 7 times I didn't get shot down. The Ai corsairs took down all 12 109s in less than 4 minutes.

The AI version of the Corsair has an incredible flight model. It seems to make turns without losing energy and it climbs like a rocket.When I fly a FW-190 Dora or Anton it kills me every time. I have been able to defeat it when I fly the Bf-109K, but it's tough.
In the reverse situation, when I fly the corsair, I can't even defeat a FW-190 Anton AI.
Something feels wrong. 

[Saxman]

I always feel that no matter how much speed I've got the Corsair simply dies in the vertical. And unfortunately, the AI LOVES going vertical (and can climb like a rocket).

Although when I can get guns on target that Late War mix sure has no trouble lighting them up.

Although honestly, there's times I've found AI wingmen all but useless.

I agree. They really need to fix this. It's not just out of step with history; it's out of step with physics itself.

And not slightly either.

It's discouraging, and it threatens the (otherwise excellent) WW2 pacific theater concept that ED is trying to bring to market.

Imagine if the AI Japanese is the same. In any fight, you'll just have to dive away and hide while watching the DCS equivalent of Kryptonians fighting out like in Superman 2.

Good like diving away. Especially if you're running Dol's Zero.

The AI on the jet side do some absolutely crazy things too, but it's way, way less extreme than in the warbirds situation.

I dove in chase, trailing a diving zero (could not catch up) and wound up ripping MY wings off.

What really annoys me is not only can Dol's Zeke outrun a Corsair in the dive, it can CONTINUE MANEUVERING. The Zero shouldn't be able to roll at all above 300mph because the stick basically freezes from the control forces.

I hear ya. The Corsair is supposed to be an energy fighter, not a slow speed turner, which the Zero was. Instead, all of the AI energy fight us, and since they have access to some other universe's physics, they win.

While this gets sorted out, I do think there's fun to be had with ground attack, and all the naval assets @Devil 505 is pointing us to. There's a stunning visual experience there. I'll throw some bat bombs & rox in the meantime. Why not.

I have not done a video on it yet, but tested the AI Mitsubishi Zeroes last night and they work great.  I was dumb enough to have 4 take off and patrol the island myself and the bomber group were going after.  I extended out ahead of the group to see if the Zeroes took off and began their patrol.  When they spotted me, it did not take long to realize I was in trouble.  Should be a lot of fun, especially with friends.  I will shoot a video tomorrow.

I recommend against using ace level AI with any of the warbirds (except maybe the Fw-190s since the AI is useless with them at any skill level). It just produces weird results. Challenge is good if it teaches you and makes you better, but having the AI just use completely insane, unrealistic physics isn't that. 

[Lidozin]

Could somebody share a file F4U-1D.lua from CoreMods?

I set both German and British AI to veteran. It did help somewhat. We still shot down 8, 2 crashed and 2 ran away, to zero losses. But at least I shot down a 109.

[Lidozin]

One can check AI FM using data from F4U-1D.lua from CoreMods. Drag polars for given Mach numbers can be easily plotted using the data from the file.

[Mossa666]

The F4U AI also seems to be very suiciadal when it comes to ground attacks. When attacking an airfield at least one of the AI Corsairs crashes while trying to bomb a target.

Here there is no magic involved, just an implemented antigraviton-graphene whirlpool, or simply put, negative values for the coefficient B4 from the file kindly sent to me are used.
If you plot the polar and aerodynamic efficiency graphs for Mach 0.2 (ground speed — 240 km/h), you can see the results of this method.
Negative values for B4 have also been successfully applied for other Mach numbers.

Maybe I was harshly pranked by having negative values put into the file sent to me, but anyone can check that for themselves.

I have modify the file for more realistic F4U-1D AI. 

Nominal weight: 12,228 lbs with pilot, internal fuel and ammo as in F4U-1D manual 12,028 lbs. with 200 lbs pilot. 

Vy_max = 15.4 climb rate from 0-10,000 ft in 3.3 minute for F4U-1D 

Ny_min = -3.2

Ny_max = 7.0 as in F4U-1D manual

Ny_max_e = 7.5

Remove all negative values in B4

tbl.effective_fire_distance = 1200 same as P-51D Browning M2

Use QvGME and put folder in there. Now I can fight with AI in ace mode. It is still dangerous if you let down your guard. 

 

Enjoy

Can anything be done about the fact your wingman just sits on his ass while you're getting shot to pieces because for whatever reason AI bandits only target you?

[Laz109G10]

Do you ask your flight to attack bandits? Do you ask your wingman to cover you? Use radio and or key bind for assistance, if not your flight won't do anything. LOL.

Maybe it's just me, but I would expect a certain amount of logical initiative from the AI without having to micromanage the hell out of them.

You expect too much!

Also I find that your wingman will only engage one enemy and then rejoin, until you repeat the "engage bandit". That's not just the Corsair but all modules.

[Dolphin887]

Guys thank you for giving us a heads up! 

[LeCuvier]

I now find that I can defeat the Corsair AI (veteran) when I fly the Spit (relatively easy) or the Bf-109K4 (hard work).
In both scenarios, the corsair's engine dies, but then the beast still climbs and maneuvers for a while before I can destroy it (typically a wing goes off) or it manages to emergency-land because I cannot fly slow enough to land a good shot.

I've played DCS for probably 15 years and never knew this. Anyone know if there is some kind of reference doc or manual that outlines some of the "nuances" or "quirks" about the AI?

 

[Laz109G10]

Try my mod. After removing the negative values in B4 the beast don't maneuver with a dead engine anymore. I said this in the "Corsair AI Overpowered" thread. Lots of the AI's are over done in other modules too. Same with the P-51D, the AI does crazy maneuvers. Rate of climb for a P-51D is 17.7m/s or 3,575 fpm not 22 m/s. When we fly these aircraft we don't get the same performance as the AI. I have never seen the AI overheat their engines, they fly at max speed with no consequences. Sometimes I get shot up in an aircraft and relinquish controls I go into another aircraft, the aircraft I got out of just keeps flying and some how makes it back to base. Lol.
