Don't forget about the search engine here (magnifying glass top right) Most questions you can think of have already been asked here before, possibly many times.
In summary, most people here will tell you NOT to use them and that's sensible advice because there is not enough friction between the metal of the motor shaft and the metal hub of the propeller and and they could spin off. They are designed for a Phantom 2 drone.
However, I bought a load of metal-hubbed P2 propellers by mistake a few years ago and my modification to enable me to use them has still never failed. (3.5 years now) If you decide to do it, it's at your own risk, of course. See my post about how I do it here
