Great comments.  Surprised me a little after seeing many other opinionated threads bashing each other.  It kind of confirmed my experiences so far in this hobby.  Most are in it to have fun which ever way makes it most fun for you.  Whether that means building from scratch or screwing the wings and tail on a RTF model.  Only one time did I meet someone in this hobby who made me feel unwelcome; I was visiting a friend in another city and we went to one of the local clubs to see if we could fly as a guest for the day.  The one person that was there, before seeing my abilities or introducing himself made it very clear that he didn't like that we were there.  Everyone else I have met with a wide variety of models, flying, and building experience have been more than helpful and welcoming.
