I will head over to Lancers Reactor to look at the tutorials at some point. Defining the hitbox has me worried at the moment. That and keeping the polygon count down. I've added some details and it's up to 8000 polys. Will have to check how many other cap ships have as a reference...
I guess the last thing to do would be work out how many turrets to put on it and where. I had the idea that a Junker ship would have a primarily defensive role protecting 'junk' and therefore have good rear firepower.
