Help!

"Twitching" Motors..


Hi all,

I just flashed my SP Racing F3 ACRO Flight-Controller with the latest Betaflight firmware, and now when I put battery on the Quad - The motors starts to "Twicth".
Motors Twitching (0 min 27 sec)


I have no idea whats wrong, the FC is Brand new, never been installed in anything.

I have checked all the soldering joins, everything else seems fine.

What could be wrong?

I meant in the Betaflight configurator what is you ESC protocol set to: make sure it is the to DSHOT 300 or 600, considering you ESC is probably BLHELI-S

Surely, we need to know what ESCs you are using. Not all ESCs are able to use Oneshot or Dshot.
