So I was watching this guy who often livestreams his P3A flights on Periscope named Dennis Wagner (if you're in here, maybe you could elaborate what happened), but during one of his flights yesterday evening, he suddenly lost control and crashed his drone in a major intersection somewhere in Lexington, KY. It was then runover by cars and ended up in tiny pieces. During the uncontrollable fall, he said he "broke a prop". He says he has around 200 flights on the props. Is it normal for a prop to just "break" after so many hours? I know props have come off in flight because they somehow unscrew themselves from the threads, but breaking?? Anyone else experience this?
