Does anyone know where I can find good sound files for FS98?  There are a lot on www.flightsim.com, but there are a few planes that I cannot find sound files for.  Here is a list:

- Airbus A340-500 (4 X RR Trent turbofans)
- Boeing 707-420 / Douglas DC-8-43 (4 x RR Conway turbofans)
- Convair 580 (2 x Allison turboprops)
- McDonnell Douglas MD-90 (2 x IAE turbofans)
- Sud Aerospatiale Caravelle (2 x RR Avon turbojets)
- Tupolev Tu-104 (2 x Mikulin turbojets)
- Yakovlev Yak-40 (3 x Ivchenko turbofans)

Thanks.
