I would like to share some information with the authors of MOD. I hope it will be useful for them
During the discussion of your work on a aviaskins.com, one of the participants,
tarakan67, suggested that an alternative to FM La-11. The changes he made to the FM, were made by him on the basis of data from the 1st book datasheet aircraft La-11:
He used the data not for a reference specimen of La-11, and for the production aircraft, which was equipped with the anti-icing system of propeller and blind landing. If this information is of interest to you, then
here you can find the file with a modified FM for La-11. And let me thank you again for your work
P.S.
If the mentioned books also interested you,
here you can find links to download them. Books, of course, in Russian, but figures and tables, I hope, will be useful for you.
