@jaxsin Thanks! This work is being developed in a private repository, see the first post in this thread for the link and explanations of how to install it. Once we have a stable version of the aircraft we will probably ask for it to get merged into FGAddon, but meanwhile you can directly use our repository if you want to fly it. As for FGMEMBERS, that's a non-official repository that has nothing to do with our work, though I believe they have forked our repository.
Also note that the interior textures and newer model are not pushed yet to the repository because we want to fix some things before, but we should do it in the next days.
Cheers!
