A few weeks ago, Aero-TV traveled to Champaign, Illinois, to sample the delights of an all indoor radio-controlled model aircraft event known as E-Fest. It was quite the weekend and we, admittedly, had a great time seeing the best in small model aircraft. While many of the aircraft thrilled us to no end, it was the wild and seemingly non-aerodynamic antics of the RC helicopters that really got our attention. How they work, what you can do with them, and how you can get one for yourself, is the subject of this two part episode of Aero-TV.
