Hello HarleyDude, Yes I had the same exact failure, I saw the one blade fly off at about 30 ft. I have been checking props ever since. I flex them and look for cracks. And yes it was a genuine DJI prop.
This is very good information. The thing I noticed about the aftermarket props was there was some rotational "slop" at the hub. Not much, but they were night tight like the OEM props. I believe this "looseness" may have exacerbated the "breaking hub" condition. By my guestimate, I was getting a mere 2 hours of flight per prop set before one failed.
Questions:
Do you know about how many hours you have on your props?
Did you have any play at the hub?
Did you have any impact damage to your props from prop strike or anything like that?
Can you post a couple photos of the hub and the embossed markings on the blades?
Thank you!!
I believe I, too, will do this flex test from now on.
Thanx!
