Easy to install/delete-
Drop the “ECHO19_FA18” folder in your /SavedGames/DCS/Mods/Tech folder. Fire up DCS. In the Module Manager, under Installed, scroll down a bit until you see F/A-18C Hornet Audio Overhaul. You may need to activate it which requires a reboot of DCS.
If you don’t like it, just delete the ECHO19_FA18 folder
Very cool! My criteria for realistic engine noise is whether it sets off my tinnitus. This is going to have me ringing the rest of the night! Will have to download and try it after go-home day, in T-24 hours.
