Title:

motor or esc to blame for crash

Text:

Hi all , i had my mavic pro crash recently due to the rear left motor stopping looking at the logs it 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 and 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 .
