If you've never been to a radio control show, you're missing out. There are a number of annual shows like the NEAT Fair in New York and SEFF in Georgia which have an enormous variety of models, vendors, and activities, and give any AMA-registered pilot the opportunity to fly too. You can buy DVDs of last year's NEAT FAir or SEFF 2008 from SKS Video Productions to get a taste of what it's like to go. There are also conventions to attend like the WRAM Show , which is all about shopping instead of flying.
In July Zero RC will be attending the SCCMAS Airshow in Santa Clara, California. If you live in the area, come check it out!
