That word physical keeps popping up, I just dont see this as a sport. I love RC, but I love my sprots also, and I just cant compare the two on levels of exertion. Yeah you need hand eye coordination, but so does the guy sorting packages at the UPS sortng stations, but that is not a sport either. (not to knock guys working at UPS, but it was the only thing I could come up with while I was typing.)
