Blackout Mini H Build

If you look at the motor from the side you should be able to see if the mounting screws protrude through the base and contact the stator coils above. It sounds like the most likely reason, particularly if one is working and you have problems with the others. If it's an original blackout frame the arms will be 3mm carbon and that is fractionally too thin for standard m3 6mm screws. Search for some m3 5mm screws on eBay and see if that helps.

Hello, yes I did have 6mm length screws, so if what your saying is correct that may have been the issue behind it all. I have replaced all the screws with M3x5mm yesterday. As for my soldering, I will be removing everything later today and resoldering so I will take a bit more care checking the joints over. The escs are connected to the PDB, the 5V step down will also be connected to the PDB and then the Naze to that. I'll upload some pictures after work today.

Update.
Last night I removed everything from the PDB and soldered on my newly bought DYS BL20A escs. I checked over all joints and wires, checked with a multimeter before plugging the battery in to find everything was working great!
However, I went ahead and soldered my 5V step down to the board, then soldered it to my Naze. All connections looked fine so I went ahead and plugged he battery in to find no power to my FC. Leaving the battery plugged in I checked the VBAT positive and negative with the multimeter and it returned 0 voltage. Upon taking my multimeter needles away from the FC I accidentally clipped the Naze and poooooof! Blew the board. Spent hours resoldering it, plugging it in to the computer nothing. Turns out the 5V step down was defective that's why I was receiving now power. Next time I'll check it before plugging the FC in. Build comes to a halt as I'm awaiting replacement parts lol.
