Hey “Fly Dawg”. I’m not trying to start no trouble, but the props pictured are “Carbon Fibre Reinforced” noted on the package, purchased & delivered from DJI (oem)
Granted they’re not completely carbon fibre, but CF reinforced. Like you most likely, I too have read the numerous posts regarding the use of “aftermarket” props & I too wouldn’t advise the use of a non DJI prop.
Never had a problem with these or the set of XOAR Beechwood props I own.
A prop that strikes the turf,gravel, cement, or tree branch whether on a nitro powered or electric aircraft will fail.
Don’t understand the failure over water neither, (OP) was the aircraft recovered from Davey Jones locker & failure attributed to a “snapped blade”?
I’ve also read the ill effects of getting fingers in the way of these CF blades producing more severe injury, don’t know who’s doing the research on that unless it would be the local emergency room counting stitch’s. CF vs plastic, most of us know to keep our hands & fingers away from spinning props, revolving blades, pulleys & belts etc..
& you DARN well better keep your wits about you if you ride a motorcycle nowadays too.'
