1. Extract the contents of the zip file "sound_UTO.zip" into the S330 aircraft folder.
2. Open the S330 aircraft folder with Windows Explorer
3. You now have a new folder named sound.UTO2
4. Open the aircraft.cfg file by double clicking on it.
5. Change the line(s) sound=0 to sound=UTO2
(If you have more than one model in the same aircraft.cfg file you need to do this for each one)
6. Save and close the aircraft.cfg file.
*You can change back to the original sound set by simply altering the line(s) sound= UTO back to sound=0
If you already have the UTO2 sound set installed in another aircraft you don't need to download again, you can "alias" the file by editing the sound.cfg file like this :
