It's not so much a matter of not wanting any of them, though I'd have to look again to see if there are any designs I would want to develop, but the fact that Wings3D doesn't often work well with models made in other programs and the fact that I haven't made any ships that I consider fully finished yet. (The Brontos being my first experiment in making a ship from mesh building all the way down to POF and table data. And I haven't gotten around to re-texturing it yet. For the big version that "cockpit" needs to go, and I need to fix some other things which will result in modifying the model's geometry, but make texturing easier.)
