Call me crazy but... Anybody make Coax mount adapters for DJI 550 type motors??

Toying with an idea for a backseat medium lifter.

I'm surprised that I haven't found coax mounts for F450/F550 arms either. I modified my arms (hacked and carefully drilled) to use the supplied motor mount plated with my Avroto motors. It took a few arms (l knew that it would take a few tries so I order a few extra). You may have to hack your own. I drilled holes so that I could sandwich the plates onto the arms. It took some work. I had thin carbon fiber plates from an old Draganflyer ship that I used to ensure that my motors were aligned vertically. It also provided extra support between the plates.

I do think there is an easier solution though.
