    Thanks a lot, Micdrow!
    H 75A is one of my favorite a/c and it is very interesting to see these manufacture's figures, which BTW Finns thought were very optimistic.

    I was looking at the climb performance according to pilot notes. At sea rate it reaches 3900ft/min, which is rather exceptional in 1939-40. It is actually higher than Bf 109 E and Spitfire Mk I. Was this confirmed by units in the frontline or it just corresponds to a manufacturer test with a very lightly armored/protected aircraft? Other tests at wwiiaircraftperformance with different propellers are nowhere near that performance.

    Look at here for the french Hawk, testing by Armée de l'Air:
    http://www.ww2aircraft.net/forum/aircraft-requests/curtiss-hawk-75a-1-2-a-3538.html#post1144200
    the best climb rate of H75A1 at sea level was 4300ft/min (21,9m/s),weight 2680kg

    with these following "movable" weights, (the armor plates was a part of ac):
    pilot 200#
    fuel 630#
    oil75#
    machine gun fuselage and his ammunition (wing guns not mounted)146#
    radio 73#
    oxygen inhaler 22#
    signal pistol 3#

    the total weight reaches= 2705kg

    Hello Warof. Many thanks for the data. I guess that the Curtiss's big wing helped with the climb rate. Do you know where I can find more information on that French trial (apart from the link you gave)? I have seen tests for Bf 109 but never for Curtiss.

    With the help of google translate, and some my editing, the ending passage reads this:
