UL controlled by shifting the pilot's weight.
Ranger M is the first ultralight aircraft to be mass-produced in Germany. More than 100 Ranger M ultralight planes were built between 1979 and 1986. Ultralight aircraft differ from other sporting planes in the simplified regulations and conditions for designing, manufacturing and operating them, and by their weight. Initially they were limited to a maximum empty weight of 150 kg (excluding the pilot and fuel). Current regulations permit a maximum take-off weight of 450 kg, including the pilot. The German Hang Gliding Association used the plane on display for a testing programme in 1980 and 1981 which led to regulations on the certification and operation of ultralight aircraft.
