Looking for 109K-4 performance graphs

[KraziKanuK]

I have the Russian comparisons graphs but no German graphs.



Help please.

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.

This are german graphs, K-4 and his engines.









The climbing performance is quiet impressive.

Thanks...is only that I just noticed the banning of Krazikanuk.
