Finished the y6 build but I have the following items not functioning...

After I calibrate the ESCs two do not spin and on motor twitches...

So motor 1 no spin

2, 3 and 4 spin

5 twitch, swapped the ESC noticed it does the same on any motor,

6 does not spin 

Thinking I had a bad solder joint I tested it individually and on worked and spun so is it a bad power distribution board?

Next, 3dr radio, I cannot seem to get the pixhawk to power the radio as with the 6 cable lead I do not get power light of any kind when turning on, after the musical tone I see no lights on the radio.

I assume these are all things I can fix,, any help is much appreciated...
