I mounted both a Hacker and a Neu to my Black Magic at one time... also a Himax, AXI, Turnigy etc...

I started with outrunners, and used an Esprit type mount. When I wanted to try an inrunner, the Neu was first, I just modified the mount to accept the motor by lengthening it and added a rear support. I don't have a picture of the Hacker mounted, but it was similar to the Neu.
