A German has succeeded a quadrocopter in record time to a height of 100 metres. The quadrocopter did 3,871 seconds to travel this distance vertically to achieve. The maximum speed for the record attempt was 189km/h.
Dirk Brunner from Munich last year with the idea of a quadcopter so to optimise it as soon as possible could increase. The critical components include the propeller, the motor, the drive of the motor, the battery and Flight Control, he observed. The final design would be a good balance between aerodynamics, weight and operation of the drive system have to offer.
Eventually the choice fell on a brushless motor. The author encountered many problems during the testing of the electronics for electronic speed control. During the testing of the motors got a lot of controls overloaded by the high speed. After a lot of broken motors and ecs systems, he knew a good combination to find, but details of which he gives not. Also limiteerde the Flight Control system, the speed, and attempts to find a manufacturer to move the softwarebegrenzing to remove produced initially nothing, but from a competitor. To keep the weight as low as possible to keep used the German parts of carbon fiber. The weight comes in at 906 grams.
The first attempt to make an entry in the Guinness Book of Records to get failed due to high sustained temperature in the lipo battery. The quadcopter this was not higher than 20 meters and fell to the piece during its landing. Within two days it was repaired and a new attempt could be.
This managed to within 3,871 seconds to 100 meters. The maximum speed was in this attempt 189km/h, with a maximum drive power of 2300W, according to the author. Brunner makes the comparison that a DJI Phantom 3 with about 4 meters per second increases, whereas its structure with a maximum of 52,5 m/s did. A Phantom 3 would, according to him about 25 seconds to 100 meters.
