Bob - the frame I linked in my previous post is made by Diatone but sold by HK. The one on Banggood is the same. Just rebadged. I've ordered another one, this time from Banggood, and it is exactly the same frame.

I would NEVER use metal bolts to attach distribution boards to carbon frames. I always use nylon standoffs. I bought a couple of kits from eBay - M2 and M3 nylon standoff kits - they come with various lengths of standoffs. I use them for mounting PDB's (I use the small ones), mounting Flight Controllers (I use Flip32 and CC3D) and mounting the FPV camera (to keep it back from the front so that in event of collision you don't smash the camera).

You don't need the strength there. Just the attachment. I can see why that guy would have had issues. As he later discovered, you weren't meant to use that PDB with a carbon fibre frame. Not Diatone's fault.

PS I ordered another frame. DAL DL265 Frame

Looks awesome, can't wait to set it up, hopefully it'll be a good replacement for my rather average ZMR250 clone. Much cleaner and less clutter due to the separation of "dirty" vs "clean" areas.
