Here is a Log File from my last flight with Cube Orange and Here 3 Compass.
After a few minutes in Auto-Mode (Survey) i Switches to Loiter in this Moment the Drone turn around the YAW Axis and came down in 4 sec.
Can anybody give me some help? I don´t find the reason for this.
Yes i tried it yesterday. All Motors runs normally. After this Test i calibrated all values new.
Than i tried a Test Flight. Started the Copter and hovering for 10 min above Ground (5m) for 10 min. All seems normally. Than i planned a survey in 60m above Ground. In the flight up to 60m the Copter turns ~90 deg. to the Left in Yaw Axis and back. And some seconds later he comes down and crashed again.
Some years ago I had a simliar problem, and was a short on the ESC cables that start to open with an very sharp edge of the carbon fiber arms. So some moments in the air, the cables touch the fiber carbon and went down.
As alvin say before, there was a large current draw in a very small moment, that coudl be a short.
I recomend to look your wires, near to sharper edges.
Thanks for your Input. I will check all Wires and put some new Motors and a new Dshot in the Frame. I won´t get this anymore. I`l hope it runs after this.
Do continuity test for all your GPS and rx wires and while checking make them little bit move so that u get confirmed is there any loose connection or not //hope this could fix u
