Forgot to take a picture, but there are two side/reinforcement pieces that get glued onto the vertical stabilizer. After you glue those on, the whole thing fits into the slots on the fuse where it can be glued into place.
I also glued the wing tower into place. Unfortunately I made the measurements while feverish and have discovered it needs to move back some. I'll be cutting it off and making another tower.
I'm hoping to make and install another tower tomorrow then I can start working on posterboard for the top deck.
