I feel like I made some good progress on this lately. All the electronics are now finished and installed. I nearly set the thing on fire by wiring up the flasher chip for the cannons wrongly...otherwise all working well.
Installed the battery under the floor, and glued the floor panels on top. I had to put silver tape under the panels as you could see the bright blue battery underneath.
I ran the wires from the front consoles down the sides, and stuck them down with thin CA. If I had thought about it I would've run the black wires down the other side, so they're less visible with the side door open. Never mind.
At this point I wanted to make sure that the door still fits on with everything else inside. Since I want it to be able to close, I used 8 little magnets, two sets to hold it in the closed position and two sets to hold it open, on the outside. They're about 1mm thick so hopefully won't look too bad once its painted.
I also cut out the windows for the front lower section of the cockpit and for the side doors, from .5mm clear plastic. The next stage is to put the front and rear bulkheads in. Oh, I also put in the LEDs to light up the rear bulkhead:
