You ask a difficult question. I think your poll does not provide enough information to get usable results. In other words, it's a rather ambiguous question. I think you will get similar results.

For instance, if a model had a 100% accurate outline, but lacked any details what-so-ever, including a painted over canopy, it might be sold as a fun scale airplane. So, in my mind, scale has much to do with the detailing.

Imagine entering Top Gun with a perfect outline airplane. It's painted in perfect colors but lacks any detail what-so-ever. Then compare it to an airplane that deviates somewhat in outline. But this second airplane is detailed to incredible museum quality. Every rivet, seatbelt, smudge mark etc. is done to amazing quality. Which one would win Top Gun (or some AMA scale contest maybe) to the letter of the law? Which one would win, considering humans do the judging? Which one would be more impressive?

I would consider both airplanes to be scale airplanes. But they would be scale for different reasons. I would prefer the one with the hundresds of hours of extra labor. Certainly, the simple looking airplane would quickly become "un-scale" very rapidly if it's outline started to deviate from perfect. The highly detailed airplane can get farther away from perfect outline before it became "un-scale".

That is why I feel the poll question is difficult to answer. It just lacks enough "what-if" information. By the way, a scale airplane is a "scale airplane" if it resembles the full scale version. Is that a P-51? Sure it is, if it looks like one. But I don't think that is what you likely meant by the original question.

Wait, there is more! What if I score a 50 for static at an AMA scale meet? Is it scale or not? How many percent from scale outline does that make it? For that matter what if my Corsair is painted the wrong color but the outline is dead on?

What a messy thing, this scale question. I personally being somewhat unknowing on the complete AMA (and others) rules on scale would love for an expert to share some thoughts on this subject.
