ElectroHub motor mount question (newbie)


Junior Member
I'm looking to build a quad using the ElectroHub kit. I was wondering if anyone can help me understand the simple disk motor mount. How does the motor get attached to the motor mount? I see that each disk has 4 holes and the photo shows 2 of these used to secure the disks to the boom. Do I use the other 2 holes to mount the motor? What is the distance between the motor mounting holes? Also, do I mount the motor to one disk first before securing the 2 disks together? Is there enough clearance for all 4 screws next to the boom?
