1.  By looking at photos it seems that the H4-3D won't fit the Phantom 4 - correct?  
2.  Is there a GoPro gimbal that will fit the Phantom 4?
3.  Will the H4-3D fit the Phantom 3?
4.  Will the H4-3D work with the HERO 5?
6.  Will using a GoPro prevent using any features in the DJI GO app?

Thanks.
