Being new to the Mavic Air I have inadvertently taken off once or twice without removing the Gimbal cover. Fortunately no damage resulted. I am about to ensure that this won't happen again by copying the behavior of (military) jet fighter planes while they are inactive. These planes have large air intakes, and while they are inactive the intakes are covered with large lids to prevent entry of foreign materials. In order to verify removal of all lids prior to ignition and take-off, large and long, flowing colorful ribbons are connected to the lids, thus rendering their presence visible from a distance. That is what I am about to do with my Gimbal protector.
