The fit and finish of this kit is remarkable. The seams between the deck plates, the deck and hull and sections of the sail (yes , subs do have sails) are almost non existent. I did find slight warpage of the hull toward the bow, but well placed clamps easily solved this issue. Instructions are a little bit vague but pay close attention and they will become clear. This is a large kit ( just short of 42 inches ) so be prepared to clear a lot of desk space. Over all I give Revel a well earned thumbs up. When finished I will submit photos ........
