Amazing it even sounds like a bit like a Merlin. As for the model. Well, when I saw it. I took all my models and burned them in a ritual bonfire.
People who can make things like that, full size or model have magic in their hands. It is my regret that I never trained for something practical or a craft. My brother did, became an aircraft engineer. I've seen some of his work. Some engineering is as better than any artform. The Spitfire, itself is a good example of Engineering as art.
