Definitions for "KRC"
The largest all electric flying meets in the world, held in Pennsylvania, the thrid full weekend of September. It is hosted by the Keystone Radio Control club, hence KRC. By the way, Keystone comes from the nickname for the state of Pennsylvania, it was the cornerstone, or keystone, of the new republic. (I used to live near Hershey - yep, you can smell the chocolate!)
