Quadcopter Won't Arm | CLEANFLIGHT BETAFLIGHT

Please consider supporting me on Patreon:   / thedroneracingengineer   If your Cleanflight or Betaflight quadcopter won't arm, there's a relatively short list of possible causes. I'll take you through all the possible things that could be preventing your quadcopter from arming, so that you can find the one that's affecting you, fix it, and get into the air!
