[QUOTE="Dronason, post: 13644, member: 553"] Seems that the related flight is FLY056 but it contains only the end of the flight. [ATTACH=full]1265[/ATTACH] Blue bar is the orientation from the compass, Green bar is the orientation from the flight controller. They are not the same but for only some moment. The missing part is where there was your issue, but also in this part it was close to declare a compass error (Yaw error). This is most probably what happened in the first part of the flight. There was large difference between the orientation reported by compass and flight controller. Then the Spark warn the pilot and give him full manual control (ATTI mode). In the available flight section, there was very large change of the magnetic module (normally magnetic field of earth is constant) when the Spark was rotating. It changed from 1900 down to 1700 and then up again. The second graph is a flight with mine where the Mag:Mod remain constant is the Spark is rotating. [ATTACH=full]1266[/ATTACH] The Mag:Mod value should not change that much when the Spark is at some altitude, either there was close metallic structure (< 10 meters) or your compass is wrongly calibrated. From the altitude and the area where it was, there is much more chance of a compass calibration issue. Of coarse internal failure of the Spark is another possibility. If you had already calibrated it, maybe you should redo and check if your procedure was correct. Follow the instructions which are given by the Go4 app. [MEDIA=youtube]MfvQBvjCfys[/MEDIA] You can also refer to [URL="https://www.spark-help.com/Spark/#HowTos"]DJI Spark Accessories & Tips - Spark Help[/URL] [/QUOTE]
