So far I like the kit. Only advice I have is to forget using the cross pins for the inside of the hull along with the center bulkhead. You do not need any of them. In fact, not having them in will make adding the fitting and glueing the deck in easy. If they are in place you will not be able to pull in the sides to match the deck edges around. Also make sure you fit the deck with the bow side parts so that their engraved slots line up correctly. DO NOT GLUE THE DECK IN PLACE BEFORE YOU CHECH THE FIT ON THESE PARTS. The fit on the hull halves are perfect if youtake your time. Great kit. Just wish there was more good photos of this sub. Does anyone have any info on the flooding holes on the bottom of the hull?
