Quoting Michael Rutherford I remember the spoilers and the T-tail from the show, but wasn't the whole thing flatter and wider? Like a big flat delta? Like the ones that were shown in the episodes on Mars? They kept taking off and landing on that massive runway (in the background, behind the alcoholic cop guy right?) Maybe try it in micro scale to better capture the size? Attack!

Quoting Archon Mitchell The shape is right on but these things were huge. Mini-fig scale would likely make it about 7 or 8 times larger. But hey, it's B5, what's not to like!
