Rattle sound in new blades

[Destin]

I notice one of my new RCP CF 425mm main blades has a rattling sound inside when shaken, as if a weight or something inside has come loose. Are there weights inside a blade this size? Would you fly with a blade that does this?

Yes there is a weight in the blades. I would not fly with them if they rattle. You got a defective blade.
