No, the only Luna Class' released for BC were 
this one and 
this one Both use the same Model....
my scaling isn't the problem...mostly because I've scaled it to DJ's galaxy class and CG's Sovereign (I used CG's escape pods as reference)  The HP from the first Luna is the one I'm using as reference.  I plan on deleting and adding some things to it and making it my own.
However I might need help with balancing...as I've never done this before LOL
ANOTHER EDIT:  The top saucer is going to be a problem...mostly due to the phaser array's weird shape...any suggestions?
