I've apparently lost my mini level, so I have to break for a couple days while I get new ones. In the meantime Enterprise was freed from the rubber bands and the inner pieces have started to go in. I worked downward from the top because, and this is very important, the guides that come with the kit, which are actually pretty great, only fit so long as the final plank isn't glued in place. So if you glue from keel upward you won't be able to check your work with the guides.
Another note on the guides, you really need to push down ward on the board that they all sit on so that it actually sits flush on the false keel, otherwise your markings will be too high. The guide doesn't want to bend so you need to apply pressure. I wish I had taken photos of the process on this side, I'll get some photos on the other side.
Personally I deplore using super glue (CA) on models like these, but you really have no choice. They have to be precise and they have to keep their bent shape in some tight corners. So I used 5 sec CA.
I made two mistakes at the beginning. 1. I didn't READ the directions close enough. I didn't realize that some of these planks were not on U1 but are on R. So I took pieces from U2-U3 which was a big mistake, as those are outward planks for the end. I thought it would be a good idea to take out all the pieces and glue them into their full length parts, this was mistake 2. Because the amount of bending and precise nature of installing these I found myself breaking all of these apart when it came time to install. I installed each one piece by piece why aligning everything as best as possible. Luckily at the start I used wood glue, so it was easy to clean off, if I had used CA glue at the start I would've sunk.
