The first day I opened my core set, I was extremely disappointed at the quality of my X-wing miniature. The TIEs were fine, but my X-wing had twisted cannons and engines pointing in various directions. I took one look at that ship and exclaimed, "If the Rebels had flown ships like this, there's no way the Rebellion could have won against the Empire!" Granted, had I assembled and painted the miniatures myself it would have looked even worse.
Later I opened my Y-wing and found that the plastic base glued to the ship was crooked so my Y-wing is facing about 15 degrees to the left of the front of the stand.
I've since gotten over my disappointment, but I got to thinking, "I wonder what other anomalous ships are out there." So the purpose of this thread is not to bash FFG or complain about the quality of the miniatures (unless it's in really bad shape!). Instead, I'm just curious what variations exist out there in the overall quality of the ships. If you've got an interesting mutant ship, I'd love to hear about it! If you've got pictures, even better! I'll try to take photos of my ships and get them posted.
