An excellent post. However, there are many more walls than you listed - which I'm sure you know. There are Free Flight vs RC vs UC. There are sport fliers vs competitors. There are club people vs non-club people. There are park fliers vs non-park fliers. There are scratch builders vs plan builders vs kit builders vs ARFs. And it goes on and on. Everyone seems to want to knock everyone else.

I've been in various aspects of this hobby for over 55 years and I enjoy it a lot. But, all these conflicts sure take a lot away.
