Chatfield also has a few jet flyers. Cool to watch, but kind of scary. Chatfield guys seem to make up the rules as they go. I don't like flying there at all, some guys will fly 3d behind the flightline!! Mile-Hi R/C is a pretty good one too. I used to fly there till I moved to Highlands Ranch. I currently have no home field but may go back to Mile-HI. www.milehirc.com if you are interested. Paved runways, some shelter, freq inpound, friendly people for the most part. Only downside is the location where it is is like prone to bad weather and wind and fog. 1 Mile down the road, no breeze, at the field 15 mph of wind or more!! pretty strange.
