FLY056.DAT is the correct file and it shows that your right front motor abruptly stopped during the flight, as shown in the graph below, where the gold line is your Mavic's height and the blue the right front motor's speed. That's also why you see the "Warning: Motor Obstructed" message in the flight log on AirData.
I can't say for certain what would have caused this, though it's typically attributed to debris getting inside the motor. Are you able to turn the right front propeller by hand and by any chance does it make a grinding sound when you turn it? A mechanical issue is always a possibility, but it looks like you've flown a number of times before this, so I'd guess that some sort of obstruction in the motor is what caused the problem.
Wow. Thanks so much for the information.
I can turn the props like usual, and there isn't any noise coming for it either.
Your advice reminds me that days before the crash, there were two times that the HD images got transmitted back turn sideways suddenly, no response to RC control but then the drone Gaines back stability and everything got back normal. I thought it was interference to RC signal, but seems it is somehow related to this crash. |
