I finished cutting out all the balsa for the rest of the top structure and glued it all together. Then using the same taping method as the bonnet I taped it all up and filled it with the remaining foam. I started to trim it up but left it reasonably proud as it still needs a bit of foam. One more canister and all the foaming should be done. I am leaving this section for now so that I can make any adjustments so the pieces fit together before filling in the remaining foam.

I then started a separate section for the rear whilst waiting for glue on the front section to dry. When both sections were dry I joined them together, I still chuckle each time I can see a representation of the actual size and what I have taken on.
After this was all dry I began to stick the sheets of 2.5mm on the bottom. These sheets should give me something to mount the skirt to and the whole section should allow it to float and keep the electrics dry should it die on the water. I began by sticking the first two sheets in the middle and this allowed me to mark out where it needed to go so the front could be adjusted an the back would be down the centreline. Working out from the centre I would just glue a sheet on each side. I then added in small pieces to make the surround as be seen from the picture below.

Whilst waiting for the glue to dry (about 30 mins - 1 hour depending on room temp) I started making other smaller parts out of the balsa off cuts. I started making a tower for the drive motor so that I could learn how best to work with the Plasti-Bond.
