To get the engine noxxles I filed down some marker caps and added some styrene detail. Not really clear why they point up, but it looks cool.
Here's a test fit of the rear section. I'm going to light this, so I had to build the engine around the LEDs. I couldn't get a decent grab of the engine so it is all from the land of imagination, which is always the most fun bit to build. The wings were pretty straight forward, just sand, sand, sand. The only way I could figure to build those bells where they attach on the other side was to sculpt them from sculpey. Not ideal, but they are barely visible. The tube and hemisphere is some leftovers from a Polar Lights Enterprise. I love how much extra crap comes with those kits.
A test fit of the whole build with the ferociously overwrought base in the background.
