Hundreds of radio-controlled helicopters, airplanes, and quadcopters buzzed through the Armory at the University of Illinois at Urbana-Champaign at the 10th annual E-Fest on February 6 and 7. Sponsored by RC aircraft manufacturer Hobbico Inc., the event is billed as the world's largest indoor aircraft show. Built in 1914, the Armory, with 80,000 square feet of floor space and a 100-foot vaulted ceiling, gives pilots plenty of unobstructed airspace. "The beauty of flying models is that it teaches so many different things," said Art Pesch, senior manager at Hobbico. "You learn how to read blueprints, principles of engineering, spatial orientation."
