Preview of the CT truck prototype, you are looking at the 'outer' face. Note that also all cables are paper made. The inner track is not yet assembled to give a better view to the construction.

The 'inner' side of the truck - the two white areas are the insertion for the inner A-shaped steering arm. The unfinished track gives a better view to the wheel details.

A comparsion between the model and the original. The 'wings' on each side in front of the tracks were added later during the space shuttle program.
