Haha, good point. Fortunately, I have given that some thought too. I think that, if it's actually necessary to build it to be used at some point, I will take the front of the upper leg (which if facing down when folded under) and have the entire face hinge back to let the tank treads slide out.Unfortunately, this isn't entirely accurate, but I feel it simply can't be. In the show, the treads come out of the lower section of the leg, just outside of where the upper sections fit into them. Again, this is a case of the shows models being unrealistic, as you can see from certain angles that the LegTrack has a slightly different shape to allow for those treads in that scene.
