    I was going to post this in Hayateace's 109 topic in ORR. But it was locked so I'm posting the climbrates here instead.

    Crimea map, full fuel, full power and boost, default loadout, radiators auto, no wind & turbulence, climb speed 260-280km/h TAS, above 6000m ~310km/h TAS. In meters and m/sec.

    Sweet robban.

    Can you extend the tests of G2 and K4 above 7km? A pattern may be developing that could be more explored above 7km. Or, you may wish to wait for 4.03. I hate that, finish testing just in time for the next Patch.

    I have a problem with that mesure, this will make a good paper data sheet but they do not reflect the real world fight climb for example the angle of climbs etc...
    It's a good start. We should try to find a test were the weight ratio/Power enter more in effect. It is why sometime performance on papers are differents than real combat performances..

    I hope i made my self clear ( i dought )

    Robban what allied aircraft is nearest to match K4 in climb up to 5000m? I know you are right person to ask this sort of questions.
    Perhaps Yak-9U?

    P63 would be close.

    I climbed to 8000m with 109's. Between 7000 and 8000m, the G-2 and K-4 has an average climbrate of 14.3 and 13.8m/sec.

    P-63 is a good climber, but it cannot match the 109. Especially the K-4. In fact there's no prop in the game that comes close. The La-7 used to be a super climber, but it has been corrected.

    Here's the P-63C climbrate. Same procedure as the 109's.

    1000 - 23.3
    2000 - 21.3
    3000 - 20.4
    4000 - 20.0
    5000 - 17.9
    6000 - 16.4
    7000 - 12.8

    Do you mean climbs at near stall speed?

    Bf 109K-4

    1000 - 27.8
    2000 - 27.8
    3000 - 27.0
    4000 - 27.0
    5000 - 25.6
    6000 - 20.8
    7000 - 17.5

    Here are the real world figures, at 1.98 ata and 1.8 ata:

    <pre class="ip-ubbcode-code-pre">
    Bf 109K-4

    Alt - Game - 1.98 - 1.8
    1000 - 27.8 - 24.7 - 22.3
    2000 - 27.8 - 23.6 - 21.4
    3000 - 27.0 - 22.6 - 20.6
    4000 - 27.0 - 21.5 - 19.7
    5000 - 25.6 - 20.5 - 18.9
    6000 - 20.8 - 18.6 - 18.1
    7000 - 17.5 - 15.0 - 16.0
    </pre>

    The current K4 has a climb rate far higher than the real life 1.98 ata version, yet is supposed to be running at 1.8 ata. And a 1.98 ata version is supposed to be added. I hope the climb rate for both versions gets fixed at the same time.

    Robban what allied aircraft is nearest to match K4 in climb up to 5000m?
    The Spitfire LF IX should be, but I don't know what it is in game.

    Real life figures at 18 lbs boost:

    1000m - 23.6
    2000m - 23.9
    3000m - 21.8
    4000m - 19.6
    5000m - 19.6
    6000m - 18.3
    7000m - 15.1

    And for the Spitfire LF VIII

    1000m - 23.4
    2000m - 22.4
    3000m - 19.6
    4000m - 21.3
    5000m - 21.2
    6000m - 18.8
    7000m - 15.7

    That's surprising, I always thought that the argument was that all planes (climb rates) in game were overmodelled by a similar amount?

    Robban, off the top of your head, how does the Dora fare against it's RL figures? (roughly, no need to test it on my account)
