Hopefully you can help me too. I have a 15020 that is cogging horribly. I have tried everything in thread with no help. It also does something wierd. If I remove the BEC (black jumper) the ESC does not work at all. Have you ever had that problem?

What are you using to power the reciever when you disable the BEC ? Perhaps your UBEC or RX pack is not supplying power correctly to the RX ?
