I've been away for a while, but back now and starting to make progress again.
This first shot shows how the interior will fit together: once painted, all panels will be glued into place. The rear ceiling/top will be glued in too. The front ceiling/top will be removable.
Here are all the parts pre- and post-primed. I'm painting the cockpit in this session too. I love how primer ties everything together...
You can see that I'm deviating (again) from the official model a bit - I don't have a separating bulkhead between the two ball turrets, plus I have built a kind of a socket for each ballturret.
Oh, and a ship needs a crew
So here is the start on the sculpt, using a 24 gauge wire, coated in greenstuff and bulked out with kato clay. Now adding details using a mix of greenstuff and apoxie sculpt.
I plan on finishing him up, then making two more casts of him to make the gunner crew.
