It sounds like you have the wrong prop guards. Here are some that'll fit:

Make sure you use screws that are made for the Phantom 3. Phantom 2 motor screws are a bit longer. If you try to use them on your Phantom 3, you will most likely destroy your motors.

I believe these (9450 with composite hub) should work for the P3. M
