Background
Section titled “Background”This alarm triggers if the motors have never received a transmitted feedback message from the fwd motor(s).
This is expected to happen on boot or Zip Exec restart until we start preflight after the motors are turned on.
If this persists throughout preflight and causes a mission failure, follow the steps below.
