To make it clear: it's not a conversion of your model!
It would be possible, but it is dificult.
The basic 3d-model is completly built by me, UVMapping and textures (only previews here) as well using Blender 2.5/ 2.6, Blender 2.49 for texturing and Incscape.
I used the very few available 3d-drawings by Fairchild, and many, many images from airliners.net, flugzeugbilder.de.EDIT:
And two flight reports, one containing a very nice cutaway drawing of the DO328: http://www.flightglobal.com/pdfarchive/view/1995/1995%20-%203237.html
The flight reports was very helpfull for the fdm, I come quite close to it, but I'm not a fixed-wing fdm guru.
JSBSim might be more accurate when it comes to engine modeling.
During searching I found of course your developement work, but this wasn't really helpful as you might think.
