RE: CC BEC causing interference or damaged?
Vulcan, I wasn't suggesting he cut the wires on the esc or the bec, just plug in an extension and chop it off or completely remove the wire like you suggested. Personally, I've got enough extensions lying around that I can just cut the wire off and not worry about the 2 dollars.
Let us know when you get the new bec, I'm interested to see if that fixes it.
