I build and assemble but don't really prefer either way. I own and fly what I like. I am in the military so you guys that say BS to the no time argument, try leaving your family for months on end and coming home and spending more time locked away building. I personally believe that some people don't have the time and some just don't want to be bothered, but either way what difference does it make to you and what you fly. There are afternoons that I get our field all to myself and I love it. We have builders and we have guys that could not build a paper airplane but all love to come out and we all have a good time. The hobby is about the people and enjoyment of flying, does it matter what they are flying?
