Next update, just a smidge of progress.
Now I've got a sheet of blue stuff to start laying out the base, which will be mounted on hardboard for protection. Also adding in the reason for it to have crashed.
Model away and I've used a sharpie to start scratching out ideas for basic lines and areas to dig in.
Possibly going to put in a squished Gonk for fun.
Now starting to build the sponsons, which currently look suspiciously solid. Hmmm.
