Alright fellas - this one is resolved.
I tried the
QuadFrame V2 mount and they turned out to be identical to the ones from my foldable pro sixcopter kit, minus the slots for ESC mounting tie wraps. Same hole. So I'll set those guys aside for another project, I suppose.
Today I received the
M325 mounts from AerialPixels and they are PERFECT! 12mm hole vs <10mm, perfect for 42mm motors like the KDE 3520's. These mounts top and bottom motor plates, so I could either build a dodecacopter (!!!), or set them aside and use the QuadFrame tube clamps and G10 strips for a simpler look. Turns out it looks great (to me), especially with
boom end caps! I appreciate the wire protection on the rounded end as well, since my only other copter piloting has been on crazy 250-class racers.

The only issue, if you can call it one, is that these mounts have the motors inward a bit vs. the QuadFrame mounts, so I will have a bit less prop-to-prop clearance. I will be testing 15", and since
@Mactadpole has used 16" with the QuadFrame mounts I should be OK even with this difference in clearance:

Now that I've got no more blockers the real build can begin!
