ugh...its the worst trying to repack extended gear into a converted model

j...all the add-ons for Flight Gear open source simulator, just like the Arado 234, are distributed as AC3D mesh...
That's handy, Borek. Blender will open AC3D models and from there to 3ds Max is an .FBX export. Sorted! (if you have Max - luckily I do)
I like how you tackle these modeling obstacles and make them work!
