nice model; I had been thinking of something like this CM for my Feds for yrs and now have the perfect model for it!
Out of curiosity, what are your specs for it? I don't have R12 but had been thinking:
Warp 24-28
Imp 4
APR 4
8 P1, 4 Phot, 1-2 DrnG
Shields, Hull, Shuttle, Lab, Control as per NCC or NCA
Again, thanks for the great model
