Trust me. You dont want to use that old wreck of mine to bash from lol. The model i made was more or less a TOS version of the SFC 1-2/op Yamato, but it was nothing more than a splice of connie parts scaled up to ridiculous proportions. I built it when i was still learning how to mesh so i dont recommend using it for any bashing.
The model Kalee is showing looks a little more like the SFB Mars class. Schtupp was working on a Mars class as well, but ive seen, nor heard anything from him in ages.
Your best bet is to ether wait for Kalee to finish his ship, or build your own. I'm semi-retired from modeling atm
