Okay, Ian - I'm with you on the money as the lead item. You convinced me.
If a person wants extremely stable and precise pattern / scale flight and has a huge budget he might go for the best of the best simulator and a really tricked out coaxial and be fully satisfied with the result. No matter what we fly, there's always someone out there who is willing to make custom components for exceptionally cool looking aircraft. What I'm saying is that if a person has very low expectations for performance flight, but has a big budget, he'll be able to find a way to spend all of his money. Inversely, as you said, if a flier has high expectations and a limited budget, our advice has to deal with that. Budget moves to the top.

So we have 5 categories of aircraft. Now I need to work the criteria that will lead to determining which slot the flier fits into. I thought this would be a daunting task, but it's sort of fun and easier than expected. And I doubt that anyone will care about this little project when it's done. But it is good food for thought.
