I found on the Net this album with the Yak 11/ Let c-11 manual.
I was wondering if anybody could do a bit of translating from russian (czeck?) to english for me, please contact me through PM if you could be of any assistance, thanks! https://picasaweb.google.com/sabo.ivan1/FlightManualC11
Hi,
I don't know much Czech or Russian but I am chief engineer for one of these beauties and rebuilt the Shvetsov radial engine, what do you want to know?
Best regards,
John
