The design of the developed quadrocopter is based on components
of the Mikrokopter Quad XL [24]. It was assembled with four brushless
electrical motors and 30.5 cm long carbon fiber propellers. Its total size
in diameter is 1 m. The quadrocopter is able to produce an absolute
thrust of 9 kg. It's empty (without battery and camera) and grossweight
is 1 and 2.6 kg, respectively. The lithium-polymer battery weighs 0.6 kg
and provides 14.8 V at a capacity of 6600 mAh. A payload of 1.5 kg can
be added. Some of it was used to mount a Sony NEX5N (16 mm fixed
focal length, 16.1 MP per image) camera system.
