Hello guys, sorry for the delay on the reply...
I believe the only way to put this baby to fly on FS is to export the model at once or in parts to a file format such like .3ds in order to import the model in 3DMax or Maya or other FS compatible software.
Blender can export a lot of file formats... but it will be a challenge to finish that one...
There's other tool called Deep Exploration, from Right Emisphere that do that type of file conversion, and it also can change the LOD levels.
But Deep Exploration is a payware tool and I don't have it.
