    First
    The inline engines should have a damagemodel for the radiators.
    As far as the books i have read, only german and anglo/us writers, the the radiators where wery exposed to fire and where often a cause to kills. The glycol was wery flamable. The Me109 could shut of one of the radiators because of this common damage.

    Second
    The P40 must have a faulty airmodel
    Look at this figures

    I have made some tests of some airplanes.
    I started at 2000 m at 270km/h and turned the engine of, corrected the yaw and tried to hold course and to keep the speed at 200km/h.
    Time of flight is how long the plane stayed airborne.
    Prop pitch automatic no flaps, no gear 75% fuel.
    The planes altmeter stood at 50 m when the planes ditched.

    Plane time of flight
    FW190 A5 (43) 3.50
    P39 (42) 4.40
    Lagg3 (43) 4.50
    La7 (44) 4.00
    I-16 (39) 3.07
    Me109F2 3.50
    Yak9 (42) 4.01
    P40E 6.14

    200 km/h is 3,333.. km/minute
    For the P40 it gives 6,14x3,3333 gives 20.46666 km which means that the P40 gives 10 m distance for every meter it looses in hight.

    You don't have to be mad on P-40, it might be the only plane with proper glide ratio from those you have tested. A standard ww2 fighter should have the glide ratio between 12-14, that means for each meter lost in altitude it glides 12-14m. Each plane has its own speed at which this best glide ratio is reached, this is the speed at which the total drag is minimal. A rule of thumb to determine this speed is to use best climb speed (from speedbar - you're interested in IAS) and deduct 10 to 15km/h. For example P-40 should be tested at 240km/h, Bf-109G at 260km/h and so on.

    Good luck with your testing!

    Interesting so the P40 is the only plane with the correct settings. I thought that it was the average that was the right one.
    Than I suggest that Maddox should take a look at all the other planes.
    Where have you got theese figures from? I am most interested.
    What about the lack of damage on radiators?

    You can see some L/D ratios (glide ratios) here:

    http://www.hq.nasa.gov/office/pao/Hi...468/app-a2.htm

    P-51 is quite average in this respect, all late war planes had a L/D ratio around 14. You can see there that Hellcat has a 12 L/D ratio - this is caused by its wings with low aspect ratio (wings are too short compared to wing area).

    Glycol flammable, really?

    Very interesting. So most of the fighter have wrong glideratio.
    The maddoxteam have a lot to do.

    Glycol flammable
    Yes very. I velded my car and the antirust coating cought fire.
    I tried to put out a fire with what I thought was water, but was water/glycol.
    It was like putting oil on the fire.
    You can see it on guncameras when the radiator is hit often torches.

    I don´t know any figures or anything, but I´ve read the P-40 was (in some texts even hopelesly) obsulete during the war.

    Even so, ingame my allied plane of choise 1942 is deffinetly the P-40.
    I find it VERY good in the game, I´d guess its too good... don´t know

    Yes I think so to it is wery nice to fly. Dont draw any conclusions about how it was during the war with the a/c profiles in this game
