Let's go to the wheels. The model has parts to make the wheels from laminating the circles. I change this to just laminate them up to 3mm with heavy cardstock. The rest is the method I learned in this forum with the masters (won't mention them here fearing I miss one or two, but you all know who they are). First, glue the radial parts with the laminated paper. Then, sand the wheel turning it so you can have an even tire. Then paint black the wheel. I still have to enhance my wheel technique, though.
