NZFF

can anyone tell me how to get some decent sound coming from the WOAI aircraft in FS9 , because the default sound is very boring
and ideas?

Cheers

FSX is blessed with individual AI sounds, in FS9 they are generic only.
If you have GNZLAP Redux, there are alternative sounds which improve things slightly for FS9 AI planes.
Just copy what's in the "Sound" folder over.
