So my first build has ended after one motor refuses to run, it just jitters.

I have tried swapping the wiring and I have checked the connections and solder joints, I swapped it with one of the other motors and that ran perfectly.

So today I am going to put the motor in a cordless drill and connect my multimeter, check wires 1 & 2, then 2 & 3, then 1 & 3 and see if I'm getting the same reading. If not it means that one of the windings has failed.

So I have to see if the Chinese seller will replace the motor, if not its game over for a long while as I have spent all I can on this build.
Maybe I will be forced to rewind myself, it will be a steep learning curve.
 
Its an intermittent problem, today it ran and so I put the motor back on and then it jittered again, I inspected the wires and found nothing and tried again and it ran. I have checked the windings under a magnifying glass and they are intact as are the wires that attach to them.
I don't want to risk flying with a motor that has a mind of its own.
 
Might check your PDB for cold solder joints. If there aren't any, you might would just have to buy a new motor. :(
