How often do DJI Mini 2 Propellers need to be replaced, and how do I change them?

Before each flight, it is necessary to check the propellers for cracks, wear, warp, corrosion, and loose screws. If any of these conditions are present, the propellers should be replaced. Follow the instructions in the user manual to replace the propellers.

Use the included screwdriver to change the propellers. Please follow the instructions provided. Remove the two blades and screws on the same arm, and replace the propellers in the same package with new screws. Attach the propellers with marks to the arms with marks and the unmarked propellers to unmarked arms. Ensure that the propellers and arms are installed securely before each flight.
