I think it's a design flaw in the way the props are secured to the motors. I noticed small indents on the trailing edge of two of my props where the back of the blade hits the hub of the opposite blade. When the motors start the blades are thrusted backwards into the opposing blades hub before centrifugal force straightens them out. Once an indent is made on the back of the blade stress fracturing will eventually start to form and cause the blade to break off near the hub
Just my observation and opinion.
Zoom in on the attached picture and you can clearly see a fracture propagating from the indent cause by the opposing hub. I'm sure the same thing is happening in the hub as well. We just can't see it until it's to late...
