Turn the ccbec around so that the input wires go between the MM and the ubec. Leave a bit more space between the ccbec and the mm, like 1/4 - 1/2 inch. That way you can put the output wire of the ccbec in the loom and it will be kept away from the input wires. I have a setup that looks identical save for the ubec is oriented as I suggest, and it works fine, FM radio too! Plenty of range, no issues.
