I got a Jorgenson Turbine years ago, the most unfortunate part was the wheels and tires, very low relief, one piece slicks with flat sidewalls. This aspect has always kept me from the build. I think he eventually got better 2 part wheels according to the add I answered but got the others instead. I would love to find a 3D printed set of wheels, and tires. I did work up a CAD version though it looks a little light.
