The AMA is a national organization with headquarters in Muncie, Indiana. Control line models are flown in a circle using a steel line tether attached to a handle held by the pilot at the center of the circle. The line length most commonly ranges from 35 feet to 70 feet.
Some models incorporate throttles operated by an auxiliary line or electronic means.
It is possible to operate other airplane devices when desired. Each airplane is equipped with a ten feet crepe-paper streamer. These planes modeled after actual carrier type airplanes and are flown from the deck of a 42 feet long simulated carrier deck. They are commonly flown using three sixty feet long control lines. Flights consist of one half mile at high speed and one half mile at low speed.
