In another thread I was asked to provide details of the E310 props I ordered from DJI for my Phantom 3..  These props ( composite ones ) http://click.dji.com/K8hsNp6ZbqFYWjCT

As you see they weigh the same, are the same size/pitch and screw onto the P3 OK.. Go get some before DJI hike up the prices : - http://click.dji.com/K8hsNp6ZbqFYWjCT

Hi Sploodge
thanks for all the info.
i have ordered a few to try out.
have you try to fly with mix p3 and p310 props.

Of course they are the same, nothing new about it. Those are called 9450 with composite hub. The P3 arrives with white 9450 composite hub props. The old 9450 had metal hub and those cost a bit more
