اسلاید 2: HistoryThe earliest examples of electronically guided model aircraft were hydrogen-filled model airships of the late 19th century. They were flown as a music hall act around theater auditoriums using a basic form of spark-emitted radio signal. In 1920s, the Royal Aircraft Establishment of Britain built and tested the Larynx, a monoplane with a 100-mile (160 km) range powered by a Lynx engine. It was not until the 1930s that the British came up with the Queen Bee, a modified de Havilland Tiger Moth, and similar target aircraft.

اسلاید 7: What is a MAV???MAV is basically a much smaller prototype of an actual aircraft and hence its dynamics are much different and tougher to understand.There are 3 degrees of freedom for a MAV: roll, pitch and yaw.To achieve these motions, there are three control surfaces: ailerons, elevators and rudder.
