    I've seen some scattered about the web on occasion. Ya never know what the engine limits are or whether the curves are theoritical or flight tested. Here's a compilation I came across:

    Don't know if that will help. Careful that those 109 K-4 claims you see are for aircraft with the serial 9-12159 prop. I gather also that the Höchstgeschwindigkeiten Start – Notleistung figures we see bandied about are for 1.98 ata which was apparently rare as hens teeth.

    The climbing performance is quiet impressive.

    Nice charts.
