I've got to agree with Bruce, poor soldering job is probably shorting out the circuit. I'm not trying to be mean about it, but just trying to help. Do you know anybody that is good with a soldering iron?? If so can you ask them to help you clean up the circuit? Best of the situation is the circuit will run correctly after it's cleaned up. Worst of the situation is you will need to get a new ESC if this one has shorted out.

Hope this helps
