Hi Chrystoff
I didn't create the model my self Hollis J Wood was nice enough to kit-bash it for me. If you want to create a Varient with different warp engines knock yourself out. I'd like to see her with LN68 warp engines.
FYI the pod on the roll bar is supposed to be mission specific and interchangable. so you can have a science pod, torp pod, and other's that I can't imagine at the moment. Have a great day.
