Nice pics... As far as the wheels go they will be just like the wheels of my model kit. The preview shot of the plane in the newsletter was a early render just to let you all know what we have coming out. The wheels have changed a lot and have got a lot chubbier like the ones in your links.

The spitfire model I have is about 6 inches long and the shape is formed from actual drawings of the side front and top views.

I try to model as close to the reference as I can but the main purpose of the tut is to teach techniques of modeling not to design an actual airplane.

For the cockpit I have not modeled the inside yet. I can add those parts later on.
