I started out trying to model the slipstream's engines... then put them at 45 degree angles and made four engines instead of two. Then I went on to add liberty-ish wings (like the ones on the defender), and overall it ended up getting a viper kinda shape to it. It also reminds me of that ship from 'the last starfighter'... what was that thing called...
The cockpit took FOREVER to model -_- it's all bars and planes, made 'hollow' so transparent windows could be done. Looking back, the cockpit came out slightly larger than I'd like... makes the engines look a bit small.
I dunno, I can always change the wings to remove the liberty appearance.
This thing, IMO, doesnt feel like a light fighter.... it's bulky and has a lot of mass - you could even scale it properly to fit two 'pilots' inside the cockpit like many other bombers have, and make it a real powerhouse.
The problem is just finding a faction that it fits in with.
The ship from The Last Starfighter is called a Gunstar. The proportions are too far off to be a direct comparison, though. And Gunstars don't have wings.
Looks almost like a missile to me.
Edit: You could make it a new defense ship for OSC. It does look like it would fit in next to a Luxury Liner. You'd need to add cushier seats, though.
