In all modded versions of the game the ini files are in the folder:
Main_Il2_Game_Folder\#SAS\STD\com\maddox\il2\objects
For the 4.14.1 ini file - you can use sfsextractor to extract them from the Files.sfs of this 4.14.1 version.
use a basic filelist.txt with the following entries:
com/maddox/il2/objects/air.ini
com/maddox/il2/objects/air_pf.ini
com/maddox/il2/objects/chief.ini
com/maddox/il2/objects/chief_pf.ini
com/maddox/il2/objects/rockets.ini
com/maddox/il2/objects/ships.ini
com/maddox/il2/objects/static.ini
com/maddox/il2/objects/stationary.ini
com/maddox/il2/objects/stationary_pf.ini
com/maddox/il2/objects/technics.ini
Be warned that quite a number of mods will not work with 4.14.1 as we have no way of knowing which changes they introduced in the main game java files (such as the gui, aircraft, bomb, fuze etc...) as they worked very hard to make the extraction of this file impossible so as to kill mods coming from other sites - Their vision seems definitively to be to take what they want from other modders work and add their own few minor mods while preventing the main modding community to go on modding. Therefore they have efficiently killed the development of mods by deliberately preventing java files classdump .
The platform for mod is now BAT and by their continuous hostile and not very clever action (an understatement...), TD have created a situation where BAT has now become Il2 5.0 (not 4.15 as the gap between 4.14.1 and BAT is so huge that we really speak of a new generation of the game, not just a simple cosmetic improvement) replacing all further versions by TD (if there are such....) as a basis for the continuous expansion of this game.
