Lew, The problem with that is most factory three views are so far off they are worthless. Factory blueprints have a drawing of the part and then all of the dimensions so the drawing doesn't have to be very accurate. As an example North American's factory three view of the Mustang is way off. Also how do you get production documentation when none exists as for WW1 or early airplanes? Also the judge has to go by the three view and pictures you modeled the plane from. If it matches that you get the maximum points.
Back to the origional question in the beginning of the thread, what do "you" consider scale. If the plane matches an accepted three view perfectly but the three view is 5% off is it scale? In my mind if it looks like the real thing its scale. If its a sport plane painted up to look like something scale its not. Don
