I love to build. I've built kits, and am working on a plans build now. I own ARF's, and BNF's and RTF's. I have no problems with people that fly ARF's, There is a guy I fly with that cannot build. (trust me, he CAN NOT build). There is another guy that physically is unable to build anymore. Both of them are way better pilots than me. I build because I like it, not because it makes me better than anyone else. It does give me a personal sense of satisfaction flying something I built though, and that is something that more than makes up for any cost difference no matter what kind of math you use!
