So, the motor on my Phantom ESC failed lately and I'm trying to find a replacement. These are specs I measured.
Motor housing: Dia 55mm Lt 67mm
Shaft: Dia 8mm Lt 67mm

It uses 28VDC and is thought to be 4KW and 150A and spins around 50k rpm. A real beast of an RC motor. I think it was for a large electric ducted fan. I'm learning but don't know a lot about BLDC's. I think it's a 6 pole but not sure. It seems to have 6 magnets on the rotor and 6 coils on the stator. Can anyone help me with this? The only really important specs are 28 VDC, 50k rpm and an 8mm shaft
