Well, I'm going by CanisD's excellent 2D schematic of the Beast from over at SFM, and I've already asked him about how he got his scaling and such. So going be that the Galactica is a little too big. And about the Pegasus, you may want to modify your model along the lines of CanisD's schematic, since it is more accurate than AldrikG's mesh currently is. Unfortunately, I'm limited to 2D projects in MS Paint, though if you want to have some new designs you're welcome to use mine, once I finish them. I'm not so great at getting stuff done, since I'm a perfectionist and always find faults with my own work.
