I'm not sure that the folks here know how much time, effort and money go into planning for a festival of that caliber. It's an unbelievable amount of work. If they were to do 4 a year (North, South East and West), You could likely say goodbye to weekly content, podcasts, new plane designs etc. All of their effort and then some would have to go into planning. Heck, I bet they are already planning for FliteFest 2016.
Look in your area for RC flight events... Here in MN there are some available, one of them is pretty large (WATTS over Owatonna). Not FliteFest large, but certianly a crowded camping weekend long event.
If one doesn't exist in your community, talk to the local RC clubs and get one orgainzed. If you don't have a local RC club, start one.
