Very nice 3D models !
The Albatros certainly isn't the easiest project.
I got the free Poser 5 and thought about building a simple 3D WW1 aircraft for it, maybe the Fokker E5 or the Sopwith Pup to makes scenes with the Poser people.
Have the free Blender 3D program but by the time I understand the interface I will be too old of age to build a model
