Feep, The rules in AMA limit how much documentation you can bring. Specificaly, it states that if you use a model as proof of scale, you must reduce the number of pages in your docs book. The three options are 6.2.A (three views), 6.2.B (photos), and 6.2.C (plastic model) and are presented as use A, or B or C. My impression is that 3 views are the desired method. I would consider photos if I had access to the specific plane I was modeling. Using a plastic model would be my last choice. I would try and avoid bringing documentation that provides conflicting views. One might even look into the possibility of creating a new set of 3 views and having them approved by an athoritive source as allowed under section 6.2.B. It all depends on what is available, and what you want to build. Using a plastic model is allowed under the AMA rules, but I wouldn't say it is the best way to go in a major event.
