Well,this model definitely needs some design work. You built it as good as anyone could, given what you were given to work with. Nice thing about this model, if you had a little kid watching this show, and put this model in his hand, I know when I was little, when these shows were first being shown, I would have been so happy to actually have one in my hand while I was watching the show on T.V.. Simple models have their place. You don't have to worry about it getting sat on, and you could easily bang out another one for a few kids to play with.
This model has it's place giving it merit.
