Austin has a nice RC field near Decker Lake. It is next to Capital City Clays where I shoot Sporting Clays and Skeet. I was out shooting today and a couple of guys had jet powered RC planes. They are really impressive and can fly up to 200 mph.
It might be a longer drive but I've seen all types of RC planes there. A few years ago a guy was flying a small Snoopy Dog house. A few times a year they have a large flying event there with probably a hundred planes there for a weekend.
