Oh good. I've sent that below to the author. Should be pretty simple but as I'm
new to fgfs i'd appreciate any help with this project.---------------
Hello
I've heard your plane could be integrated into Flightgear under the GPL
licence?
If yes, I'll have a look at it and send you a huge thank you from the FGFS
community.
Without licence restrictions I might even do a x-plane version, but I suppose
that's not what
you would want, right?
I've done a PC-12 so I'm familiar with Blender/X-Plane but however FGFS is new
to me.

Let me know if that's ok for you?
Kind regards
Michael Sgier

On the forum thread one post says that using an on-line transalation engine
works OK. All of the screen shots are of Blender with an English UI.

If you go to the web site it should have a statement about all of the models
being free to use in FG and it's projects. The author of the models (and
ebook) was told when asking for permission to use these that FG needed these to
be GPL compatible so he is aware that these will end up under GPL if they are
used in FG.
