Lol, I wish they were. Google Sketchup doesn't support rigging, so I can't animate them or anything along those lines. Instead I use floating articulation points to move the parts into the place I need them. The floating articulation points could be used as a reference for rigging, though. I've never had much luck exporting to Blender for rigging though (Blender is over my head. D: ).
Awesome work buddy :3
Thats insane even for a mecha! I wonder how much fuel is used for the boosters alone? XD
