not a mod.
It's just a collection of files that have been in the game all the time, plus two lines of Java Code.

Gear Doors for the Hawk-81A-2
Installation:
Copy the folder "Hawk81_GearDoorNOTMod" from this
zip package to your game's mod folder, be it
"MODS", "#SAS", "#UP#", "#WAW" or whatever.
--- This is NOT a mod ---
It doesn't qualify for being a real "mod" since it
only consists of files that exist in the game
already, plus two lines of Java Code.
Credits: None. It's been there all the time.

Q&AQ: Do I just have a Déjà-vu? Didn't I see this mod elsewhere before?
A: Maybe. Who cares?
Q: If this mod existed already, why do you release it here?
A: Because "elsewhere" there's all types of restrictions applying to it, here it comes without gongs and tinsel.
Q: So there are no differences between this release and the "other" one?
A: Oh sure there are. This one doesn't change the stock game's flight model since it fits like a glove already. "Elsewhere" you get a wet dream flight model. Choose yourself

Q: But isn't there a copyright on this mod?
A: You're kidding. This isn't even a mod.
Q: Could you explain the "wet dream" flight model a little deeper?
A: Sure. See below.
Several people like to claim that the "Flying Tiger" Hawks would come with an extra boost giving the engine 100hp more.
Unfortunately this lacks any sources.
According to available sources the engines were low octane models like all others of the same production line, which makes perfectly sense when you take the low quality of fuel in the CBI area and the deliberate supply situation into account.
The "wet dream" flight model found elsewhere even increases the engine power by 320hp (!!!) when WEP is engaged.
That's beyond imagination.
Furthermore few people like to misinterpret the improvised radio equipment of Flying Tiger Hawks and claim that this would significantly reduce weight.
Available sources state that the Hawk's wiring had to be
adjusted to accommodate the RCA receivers used.
The fact that these RCA-7-H receivers were not as reliable as the original US or british ones doesn't mean that they've been a featherweight.
This change definitely doesn't reduce the plane's weight by 374kg (!!!).
Last but not least the damage model is beyond good and evil.

This would put the Hawk in the same league like an IL-2 1941 model and make it tougher than a late war P-47.
That's silly.
The engine power and weight changes furthermore would make this Hawk an UFO.
See "stock" Hawk in blue and the "wet dream" one in red:

A Hawk running 600km/h+, 40km/h more than the stock one? Aha...
Well, let's see how it fights against it's opponents.
You will see which is the stock FM and which is the "wet dream" one yourself.
Hawk vs. Ki-27:

Hawk vs. Ki-43:

Hawk vs. A6M:

Hawk vs. Ki-84:

If such a "wet dream" flight model was true, Japan would have lost the war in 1943 and the US would have had no need to build any other plane after this Hawk.
That's why this Hawk deserves it's gear doors without all that stuff attached.
