Rick,
I had no idea Tony held on to it, now I know I will never get it back!
I remember posting the original design drawing, photos, and your project to replicate it. Both the original and your reproduction are beautiful.
The design I made followed the "Panzer Iso" that Tony made from my concept and after that one we discussed the Starship. I did the full-size drawing (posted below), showed Tony, and he said, "You cut out the center section and put it together (the rear end) and I'll finish it." He wanted skin in the game for this experiment and the center section was a labor of love with the radius inside corners, and a lot of Dremel discs.
The motor box was deliberately so tight that the motor could be soldered directly to the frame on two sides, only two gear sizes could be used, again deliberate, and although it was too stiff to handle better than other frames it was a beauty I think beyond compare (IMHO).
