Fixed wing proportions (they were a perfect hexagon before, my bad).
Extruded the rear a bit and added a cosmetic engine.
Edited the ball-to-wings connections.

Made it of Trinium instead of Iron. I like the texture of Trinium best. Also, made it drivable. It's a bit slow, but if you want to edit it, now you can move it and turn it so you can get light from a desired angle. Needs only 1 crew.

Fixed the solar panels a bit.

Added windows. Credits to deep for inspiration. I believe it's at 198 blocks now
