The models I've seen so far on the forums are amazing.
You guys could make a killing if you started marketing your talents to Warhammer Enthusiasts. You can make top dollar building their armies for them . Though since it isn't exactly the same genre I don't know if you'd still find it fun.
Ever thought of making working landing gears? Would be an interesting challenge to see if you could build a model airplane that had limited functionality (nothing motorized).
