Agreed, keep things in one post, or maybe one post every once in awhile.
On another note. Ship looks good, and seems functional. Not more you can ask for.
One cool thing about the thruster plumes is that they still show up if you don't place a block directly behind them, so you can do a layer of ice with some lights in key areas one block behind the thrusters to get the nice look of glowing engines and retain the plumes.
