I would give my left nut to know what you know. In getting ready to learn about how to do the things you do, I looked at a lot of images. Your work is some of the VERY best. I love the above image, but GOD I would like to see you give it age and dirt and grease and such. I love that, from an engineering point of view, you think things out. The threaded rods are beautiful. They also make a great contrast with the field of red. The orange tinted glass was genius.
I'm thinking I forget the electric motors in each wheel's hub, so I'll have to resort to some kind of jet engine suspended beneath the body, between the legs. Wait and I will upload a new design with a detachable jet underneath. Your comment made me think about what was missing!
