It will also be useful to you in life, not only on sas1946
This is not your local pub, keep it civil please, thanks.
For all others: The FMs can be found in the forum section "Моды для Ил-2" ("Mods for IL-2") -> "Первым делом, первым делом - самолеты" ("First things first, first things first - aeroplanes").
There's a thread called "Новые самолеты. Обсуждение." ("New aeroplanes. Discussion.")
Unfortunately it's a mess of all sorts.
The new FM for the P-55A can be found on page 482 (!!!).
Yes, you read correctly. There's 481 pages with other things before the post you're searching for.
When you download a new FM from Vasya, make sure that you understand the contents of the file provided.
They usually ship with no readme whatsoever.
Most of the times, they ship with one or more encoded flight model file(s). If it's more than one, find out which is the right one. There will be no clue.
Sometimes plain text flight model files are provided, too. Whether or not they reflect the state of the encoded flight model file(s) is a matter of flipping a coin.
Sometimes there's further files being shipped, most of the time they're useless, sometimes they're mandatory. Again, there's no clue, no readme. YMMV.
