The Smoky Hill Model Flying club of Salina Kansas is mostly R/C, but we do have a control line circle that is used by 4 of us. Since I do fly a little R/C the club asked me when they put in the field if I would like a control line circle. At that time I was the only one but told them it would be nice. They put in a concrete takeoff pad and a concrete pad in the middle of the circle for the pilot, and we have a nice buffalo grass circle. The club has a well and an irrigation pump to water the field. All in all they are all a great bunch of guys and most of the newer R/C bunch had never seen a control line model fly before. Always fun to watch them when they see their first wingover.
It use to be that model clubs had both years ago, but then the R/C clubs became exclusive. Now I see the trend going back to including control line again as most clubs, at least the smaller ones, like as many members as they can get.
