I crashed my Eachine quad with a cc3d board. After two motors would not run I tested them on a different spot on the quad they both worked. So I thought it was the power distribution board as a component had broken off. I replaced the board no good. I then went in and tried to test the outputs for the motors in Libre Pilot program on the pc the same two motors will not run. I'm thinking I have a bad cc3d board as all the wire and connections look good. Has anyone had a board go like that?

No, but the first cc3d on mine the receiver connector came off before the first flight. 

You might try swapping the pins on the short cable from the cc3d to the pdb. Swap the pins for the channels that aren't working for the two that are.  That will tell you whether it's the cc3d (or it's settings) or pdb.

That's a good idea running pwm receiver and I have a ppm receiver I may try that.

I have a board that had a problem with a dead motor#1.  I moved the ESC (servo) cable for that motor to FC position #5 and made the appropriate change in GCS, and it started working fine again.  Configuration->Vehicle->MotorOutputChannels

Hi. I have a cc3d where number 3 is the problem output. So if I move it to number 5 how do I set it up as a quad?

[TheOtherCliff]

GCS->Configuration->Vehicle->MotorOutputChannels

1->1
2->2
3->3
4->4

change #3 to say
3->5

Make sure to look up at the top and make sure that the bank for output #5 is set the same as the banks for the other outputs.
