[QUOTE="Dronason, post: 8714, member: 553"] Thanks for sharing your DAT file. First of all I am not THE expert on such analysis but I am on same boat to learn from mistake. At first I don't see the motors activated, the power is like 10watt so it is more standby mode. When motors are on it is typically around 60W on mine. There is also no mark in status of take off or any status change. So I have a first doubt if the DAT file was from a flight. As said I am also on learning curve. In DJI assistant, it is not that simple to found the right flight log, it can be confusing. This is the full log, In RED marked near the time scale is some activity and is zoomed in next picture, BLACK is some standby time and BLUE is power-up. In general, GPS satellites was not that much 5 to 9. Magnetometer reported too high value ~2000, it is typically 1600 on mine which is the value you get too at end of record. This mean there was some strong magnetic interference before it moves. The value changed at start of RED time area but the final value was still high. [ATTACH=full]804[/ATTACH] The RED area, zoomed: [ATTACH=full]805[/ATTACH] There was only a throttle stick up action on the RC. But there could be some glitches as Spark is new and the program CsvView was recently adapted to support the Spark. The RED area (16 seconds) is maybe the move and crash. Then in the blue area you pick it up and switched off? As said at start, some elements make me thinking that it maybe not the DAT of your crash. Here is a normal flight with mine plotting the same parameters. [ATTACH=full]806[/ATTACH] [/QUOTE]
