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.
DroneFlying, did the other motors also stop, or did they try (without success) to compensate?
One possibility thought is bird collision causing overcurrent and shutdown in one motor.
However, I'm betting on a motor driver failure, Can't tell if the internal damage is due to crash or electronics failure without taking a look inside. It's interesting that the drone was still communicating after the crash. |
