One ESC Stopped on X4

Hello world,

My left lower motor sopped mid flight.
I have the batch 4 -14S - 4 sets of battery’s, of the X4 with the X-Rotor pro HV 80A and the extra external capacitors.

After repower the whole system and test everything on the ground I could not reproduce the issue. When relaunching once more, the motor stopped almost immediately after takeoff. When landed and rebooted once more, doing some ground test, no issue at all.

If someone have some experience with reading out the data from the ESC, please informs how to do this as I’m interested in the error message of the ESC.

I cant find any manual of the ESC but the website claims it should be possible to read out the ESC.

Thanks in advance!


Do you have a microsd card handy that you can insert into the hub?
There should be CSV logs on it once you reboot it and try again

I have a micro SD card in the hub from flight one but when I insert it in the computer there is no data on it. Any idea what can be the reason the SD card have no logs on it?

If I think about it the SD card slot on my hub probably never worked. When I wanted to update the software on the hub I had to do it with the NUCLEO programmer because the .bin file was never detected on multiple types of SD cards that I put in the SD card Slot on the hub.

Make sure it’s fat32 format and not larger than 32gb
