Peter James' jet soundset for FSX! I have been tinkering with soundsets for years now to achieve what I believe is absolute perfection. This soundset is based on the real default soundsets, with a few custom wav files to override existing ones. Installation is simple. Put the wav files into your main sound directory right off the root FSX folder. Then open up each of the four jet zip files, place the two or in some cases no wav files into the appropriate jet's sound folder overwriting the existing one(s). In some cases, no new wav files are included as I have used the default engine set. Then for each plane, copy and overwrite the existing sound.cfg file. You're done! Sincerely, Peter James
