Thanks for contributing by purchasing a mug! As for the specifics of the ship, well even the fuel is really an in-joke as it's because Doug likes Stargate, It's up to you for how powerful you want to make the ship and so on...
More interested in functionality I guess... Not so important how it does something, just that it does it and looks plausible doing it.
I see a lot of people trying to make sense of the default settings, Cairans post above as a prime example, and that's fine, I'm just not sure it needs explanation. It probably doesn't matter what settings you use, you're still experiencing the same physics, its the same simulation, it just becomes a different vehicle for exploring that simulation.
Thanks to Doug, By changing the config file, you can make it suit your ideas and then share that with others, and you would be encouraged to include as much documentation as you felt necessary.
Here are a couple more pics of the interior, i've made further changes here, visible are a couple of 'sanitation units' - Toilet/wash facilities. Although not shown at the other end i've partitioned off the cockpit/ flight deck and added a crew rest area and crew sanitation facility. I've also added a mechanism for the rear door, so it can lift out of the way of the bathroom doors and allow access to the bay, a CHM or dorsal docking collar if either are fitted.
(if one of them looks a little dark its because i'd accidentally left about 20 point lights switched off - all this lighting will be baked into the final textures.)
btw MachJok, if you're still with us it will fit comfortably into a bounding box 30*20*9 meters, thats with gear down and nosecone closed, with gear up and nosecone open it will fit into a slightly smaller area.
