All fo my models have taken less than a day or two to build. One day goes in preparing the blueprints and the development of parts– at least six hours. Another goes into cutting, pasting and painting (if needed) and that often finishes quickly, but in case I need to make the model more detailed and more accurate, it will take longer. I don't use pre-drawn kits for my models. All of my models look very primitive compared to most of what I find in the same category. While there are many which are prepared from downloaded or printed kits, I'd like to know how long they take to build, especially if they're built from scratch, the way I make them.
