Are props for the Phantom 2 & Phantom 3 interchangeable?

Go back to the very beginning of this forum - the part where you can see the subjects:

etc.

Select "FAQ" and look at the first post - I think item #8 is applicable in your case.

The props for a Phantom 2 have aluminum hubs and they will spin off in flight and crash your P3.  (This is due to the dynamic motor braking on the P3)

The New 9450 props have composite (plastic) hubs that thread on and grip tightly preventing the props from spinning off.

P3 props can be used on the P2.  But P2 props should NOT be used on the P3.
