I've been trying to get a hold of some of the original B5 digital models for reference. I've had a little bit of luck so far.
Unfortunately the Vree ships are not one of the ones I have.
I'm trying to figure out if the Star Fury Engines are inline with the direction of travel or slightly canted inwards.
On the digital model I have the engine are canted inwards. But some publicity reference from the time have them pointing forward.
