Package check. Check the system package contents (see chapter 2.1).
Drone check. Make sure that all drone systems are in working order and the batteries are charged.
Replace damaged propellers with new ones: vibrations from damaged propellers cause the "jello" effect and blur in images.
Memory cards. Make sure that there is enough free space on the camera memory card and on the LR1 Control Module microSD card.
Payload connector. Make sure that the contact pads of the X-Port gimbal connector and the drone Skyport connector are clean, undamaged and free of oxidation.
Lens. Check that the front lens element is clean.
