So I recently bought a boat load of Dal 5045 props. After using all my HQ's I put the Dal's on. I noticed some high throttle vibrations with these props. I just thought my PIDs needed to be adjusted a little so I was taking it easy for the remainder of my flight  , when all of a sudden my quad just throws a blade. I thought I might have just hit a branch or something. I replace the broken on out threw another battery on and 3 min into my flight same prop lost another blade. Checked out my quad and everything checked out. Again replaced the prop. Flew for a few min and down came my quad, however a different prop let all 3 blades go !! Has anyone experienced props just breaking at the hub in-flight?

when you say "throw" do mean the whole prop came off like the prop nut came off? or just a blade broke off the hub?

blade broke right off the hub Jimmy. Not once but 4 times, im thinking a bad batch of props.

I did hear of one other report of DAL props doing that exact thing. Turned out the person had knockoff DALs. Are you sure yours are legit?
I've broken arms in crashes that only bent the DAL props.

I got them at readytoflyquads . Maybe ill give them a call in the morning. I have 6 more packs and Im afraid they will blow off. Is there any way to know if I got the counterfeit props?

The props I have (bought from RTFQ) Must be fake. From what some posts on rcgroups say is they will have a DAL printed on them, the one's I have just have 5045 stamped on them!!

the authentic ones will have "DALPROP" on one blade and the size and pitch on another blade.

Thanks Jimmy. I just have the blade size, no DalProp. I have always had good luck with RTFQ , I guess my luck just ran out
