Well, just got done modeling the Oberth, so now comes the hard part, the texturing... I think I'll start the Excelsior, Galaxy, and Nebula, because now that I know what I'm doing, the actual modeling takes no time at all (Plus the galaxy can be tweaked to a Nebula pretty easily).
I'd recommend moving the engine trail hardpoints to the area between the shuttle bays - that's where the Miranda's impulse engines are. Also, I think the little dome dealie under the roll bar should be glowing blue, not flat grey. Oh, and if you could put hardpoints on the torpedo launchers on the pod, that'd be awesome.
Done, and done. Texturing is a little hard for me, because I have some serious color blindness issues (my first texture for the miranda was completely pink, and I had no idea until a friend told me...) so yeah, the more cool glow-y things I can put on the ships, the better. Now, are you looking to turn the miranda into a capital, or can you add more weapons to frigates? I've done very little with code, so I have no idea if you can. I'll make those changes and re-upload the model. Just let me know what you are up to, 'cause if you manage to make some cool torpedo effects, I'd love to add them to my own games...
If I could model, I would love to start on creating a Nova class starship or even the Nova class variant, U.S.S. Rhode Island (captained by Kim).
Nova would be sweet... I'll have to look into that.
