Build time is probably only a couple of days at most, but actual start date to finish date varies. My current build probably has about 3 days total build time but I started it over a year ago and still have quite a lot to do before I can call it done. Granted it is my first build in a very long time and the skills are very rusty, had to redo paint about five times before I was happy with it. I don't know how some of the guys on this forum can build so many exceptional models as quickly as they do. I really envy their building skills. Perhaps with time I will be able to do more than one model every two years and get up to at least two models in a year. LOL.
