gruntbull commented on a Build, Beebrain Floppy Whoop   Nov 21, 2016  

Whiffles, I built a very similar quad - I am only missing a mount from what you have (waiting on a battery to test it out, they were back ordered). The USB will not power the motors or the vTx as far as I can tell, they might, but I was unable to get it to go, using CF that came stock on the board. May change to Bf after I get it running, but that requires some more solder to go into bootloader mode.

Oh bummer about CF. I wonder why they don't just stock them with BF from the get-go. I don't think you need solder if you just carefully bridge a small wire into bootloader. It'll probably require a second pair of hands to plug it into the USB slot though.
