The rear hull is taking shape. I am reinforcing the edges of the foam with styrene (plasticard for our friends across the pond). My styrene source is actually pretty good since it's free. I like using the blank credit cards that come with credit offers or empty gift cards. I have been saving for some time and have a stack about 1 1/2 inches tall. My filler of choice is drywall joint compound.
The cockpit module is coming along nicely.
