title_body: Betaflight with Mamba F405 MK2 stack 40A ESC's and XING-E 2207 motors problem
upvoted_answer: If you have airmode enabled as a feature then the motors will spin on arm no matter what other settings you have.
  It sounds to me like you may have accidentally set your ESC's to bi-directional in BL-heli configurator which is NOT the same as bi-directional DSHOT protocol.  Check out this video for explanation on the difference : https://www.youtube.com/watch?v=DXfAnCLr3q0&amp;t=65s
