Features of the addon are described below.
Mod creator - Sovietmann
1)The addition changes the models of Bf-109 fighters to historically more accurate ones.
2) The basis for the addon was the reworked mods "Ultimate 109s v2.1 for HSFX/UP" and "Bf-109 Ultimate Pack v3.1" from the site SAS1946.com
3) The addon was originally intended for early versions of the game, but was adapted for everyone from v4.01 to v4.15 (on earlier versions it should also work, but due to the lack of them, it was not tested).
4) For ease of installation (full or partial), the 3do and class files are placed in separate folders
5) The Bf-109 folder (improved_default_models) contains reworked models from "Ultimate 109s v2.1 for HSFX/UP". The remaining folders contain reworked files from "Bf-109 Ultimate Pack v3.1".
Note...
Installation is standard, via any JSGME.exe file.
