this mod is not for 4.11.1 version of IL2 simulation and HSFX 6.
Just for you (I hope you know that you owe me a cup of coffee now at least) I grabbed my HSFX 6.0.17 install and dropped this 109 pack in and added the corresponding lines to air.ini from readme.txt in front of the existing 109 entries (note that most of the variants of this pack do exist in HSFX 6 before already).
Works from the scratch.
Then,
just for you again, I grabbed my 4.11.1 modact installation and did the same as before. Note that this requires latest SAS buttons to be installed.
Works from the scratch again.
Your turn now.
"HSFX 6 == 4.11.1"
Not quite.
4.11.1 is a subset of HSFX 6.
Even this is not precisely correct. There are some incompatibilities where HSFX 6 modifies stock 4.11.1m classes (ask Dogfight Server operators, they can tell stories about it).
P.S.: I tested
This could be a good chance for you to go on testing until you eventually figured how it works right.
This will save you from troubles when installing other mods in future.
