Motor one not spinning like esc problem
Tried reflashing could take it apart to see if it’s the motor or esc?
Hi
Yes that does look like it could be an issue with the ESC. Could I ask if you can go through this guide to help narrow down the issue to be on the motor/ESC, and also to double check the connections?
How to troubleshoot your Motors and ESC (Betaflight)
I have also passed this onto BetaFPV support to request a warranty replacement unless they can offer a solution to this.
Kind Regards
