Well, the short answer is that it works. It doesn't automatically install into a user-defined directory, so I had to spoof it into a fake P3Dv4 folder, then add it to v5 using add-on.xml. I'm still getting a sound initialization error on startup, but I think I can sort it out, plus sounds seem to be working fine. The rest is a bit of RTFM work figuring out how to work the FMS etc. but she looks fine!
