| - | Replacing the lower case half (with the belt hook portion) is the most common reason for replacing the MiTail case. This requires that the case be opened, the two batteries taken out of the case, the control board removed, the four servo frame mount screws be removed, and the servo pulley be removed from the servo.

| The most likely repair would be to replace the USB connector or a damaged tactile switch, which are reinforced with hot glue. Removal of the hot glue is possible, but requires care to prevent components from being removed from the board, along with the glue. The best method to remove the hot glue is high-concentration Isopropyl alcohol (IPA), also known as rubbing alcohol. Soak a Q-Tip in rubbing alcohol, and working your way from the edges in, brush the dried glue gently with the Q-Tip. As the alcohol weakens the adhesive, lift the edge and peel the hot glue away from the board surface, reapplying the alcohol as resistance is met from the glue. | The most likely repair would be to replace the USB connector or a damaged tactile switch, which are reinforced with hot glue.
