I check over all my UAV's before I fly and the Anafi is no different. Did my pre-flight and checked the blades. All good. Went for a 5 minute flight and landed. As I was picking the Anafi up from my landing pad I saw what looked like a chip in one of the blades. Sure enough one blade was chipped. It was mentioned on another forum it might have been caused by forcing the blade against the opposing prop screw across the motor. Not sure how that would have happened as I am very careful when setting up and putting everything away. Who knows, just make sure you check out your blades before flight.
