Firstly you must change all your propeller blades before attempting another flight:
⚠ PROPELLER BLADES ARE INSTRUMENTAL FOR FLIGHT INEGRITY AND DELICATE PIECES OF EQUIPMENT, AND EVEN “MINOR” CRASHES CAN INVISIBLY DAMAGE THEIR STRUCTURE.
Set up your ANAFI series drone for a flight.
Check the ANAFI series drone page of FreeFlight 6:
Any permanently damaged element (gimbal or motor) will appear in red – if an element is damaged, refer to point 8 below.
If no element is damaged, carry out the calibration(s) requested by FreeFlight 6 (gimbal, magnetometer, or both).
Fly your drone in a mission, take pictures and videos.
Check your ANAFI series drone pictures and videos to see if your drone’s horizon if offset.
If your horizon is offset, carry out the “Correct horizon” procedure
Refer to How do I make my drone's horizon straight again?
If the “Correct horizon” function cannot make your horizon straight again, it means a part of your gimbal has been deformed and your drone needs service and a new calibration.
Note that if the crash has damaged a component of your ANAFI series drone which is essential to a safe flight (such as its vertical camera or its ultra-sonar), your drone will not be able to take off and a FreeFlight 6 alert will be displayed.
