    Hi all , i had my mavic pro crash recently due to the rear left motor stopping looking at the logs iit appeared the motor was still getting voltage but the current dropped , in testing the motor it seemed a little tighter to turn than the others but spinning it ant testing the output voltage it seems to be the same across all phases and winding's seem ok testing with millivolt meter .
    Here is a screen shot of motor speeds ,current,volts .
    The esc temps seem pretty much the same .
    I have replaced the motor but not sure if i should replace esc bord too .
    Here is a link to the full log .
    I can post the link to flight data if required .

    Why didn't you contact DJI regarding the issue, no warranty?

    No , no warranty or insurance , i sent logs to DJI , they just want me to send it for repair which will cost a small fortune no doubt , its almost repaired i'm just not sure if i need to change the esc

    If you've replaced the motor and it operates properly now, I wouldn't worry. Except in rare instances, ESCs either work or they don't. There's no in-between

    Threaten it with a soldering iron.
    Only hold it like your going to stab someone though. :mad: works for me.
    Dji should rename themselves to Jpi
    Just Post It.
