Anything metal vibrating together is never a good thing in the signal department. I've seen several cases of metal vibration glitching the Rx and causing a crash and they all worked fine on the ground off or at low throttle. Your wires are coated though and shouldn't cause any problem unless they wear through later on. It may or may not effect your Rx. It all depends on what kind of RF, if any, is generated from the metal vibration.
