Heya Elkinallen,

I have been modifying different aircraft in MS Flight Simulators for a long, long, time and (I'm not trying to rain on your parade) the hardest thing to do is to re-assign *.wav files for aircraft sounds.  You could modify your 727 Sound.cfg file to add these additional sounds but it would be a lot of work.

I have a 727-200 for my FS 2004 and with it I use a Sound package from Eric Cantu called fx7222k2.zip.
An excellent package which includes all default sounds plus startup and shutdown.

You can pick it up here:

Just click "I Accept -- Start Download"

I hope that this helps.

I found and downloaded the 727 sound that you advised me on.  It is SWEEEEeeeT!
The thing sounds real!! The engines sound real. It is great!
Thank you.
