Matt, The outline and color judges are 15 ft from the airplane so at a minumum you should do the details visible from that distance. The crafstmanship judge can get as close as 4 ft so details like brake lines, weathering, and yes the cockpit make an impression on the craftsmanship judge. New for this year is best scale cockpit at the championships. What it really comes down to though is what does it take to satisfy yourself. To me getting all of the scale details possible in the airplane is as much fun as the competition. There is great personal satisfaction at creating an airplane that everyone oohs and ahs over. So do the best you can and enjoy the experience. Don
