I am replacing the landing struts on my Q500 4K and after I removed them I noticed a little wire taped to the inside of the right side strut. It is black, insulated and has some kind of component in it, with a bare silver braided end at the ground end. I assume it's an antenna of some kind.The fuselage end of the wire doesn't look like it was attached to anything and I can't see any place it would be hooked up to the fuselage but it doesn't seem right that it would do anything if it wasn't hooked to something. Since the instructions don't offer any exploded view or parts nomenclature I don't know what it is or what it does. Anybody know about this little wire?
