omg those are awesome.
as a huge fan of Firefly, I have to say you really did capture the feel, and the process to come up with the ship, and the class.. that was very well thought out. Feels very authentic. And holycarp that's a goodsized printout!!
yknow, it occured to me.. it's too late now, but you could have had it set up with a sensor array that opens up over the cockpit for extra range/sensitivity .. or a ramscoop type thingy so it looked like it had jackrabbit ears when deployed
