If you're planning on making any other ships based off it, I'd be happy to provide reference material (or rather, I'd be happy to have an excuse to play that again).
Please. I badly need more Terran Battlecruiser reference shots, as I fear I made it rather too short. If you can provide enough good reference shots of the other ships I might take a stab at making those, too!
Top down shots are best for BSF obviously, but any shots that get me an idea of the ship's armaments are good. I got the fighter bays for that BC off an old low-angle shot that revealed what looked like launch tubes on the underside.
If I get enough reference material to properly polish up the hull, I can start work on the variants - Proton (Blaster), Missile and Quantum (Tachyon) armaments.
Basically I started with the Ion as it was the easiest of the weapon types to emulate. The stock beamers have been upgraded to Ion Cannons, with very good coverage (180). The mid-wing megabeams, nestled slightly into the hull, are Ion Blasters, with extremely good coverage (360) but atrocious tracking (0.50). The Scatter Lasers are Ion Turrets, most have 180 degree coverage, and are stock damage/range. The demeter bays launch 10 drones in fairly quick succession, but take about 20 seconds to reload after - and will be the only "constant" feature between designs, not counting the generators. Finally, the center megabeams are Turbo Ion Blasters. They pump out an absolutely ridiculous
amount of damage (roughly 25 per frame the beam is held on a section), but have very limited arcs of fire, terrible tracking, and take 50 seconds to recharge between shots.
The Missile BC will use a mix of missiles and plasma charges (torpedoes) with flaks, the Proton will use a mix of blasters and modded gatblasters with flaks, and the Quantum will use a mix of Drivers and Cannons with a Megatachyon as it's blaster weapon and particle guns for PD.
