Closeup of the glued-on fuel tank area. Aleene's Tacky Glue dries clear and pliable, which means this
mechanism with it's fuel tanks can be picked up and handled with no problem, as the glue is flexible and strong enough
and most importantly, the dried glue is *not* brittle.

You can't see this rather ugly looking underside when the model is right-side up.

Since this picture was taken, a little more glue was added to the 'air gap areas' on the left, between the trucks on the left
and the fuel tanks, then painted black, so that the fuel tanks would look solid when viewed from the 3/4 angle.
