Well thank you very much. I built it backwards and the engine nacelles droop in the back, it's been sitting on a shelf for a year because I was disgusted with it, I finally finished it. I might scratch build one to make up for my stupidity with this one, or I'll just design a new tug. I've had one in mind for about 6 months now, using the 1000 scale Enterprise re-fit as a base.
