There has been some discussion on other forums about shielding the GoPro with copper or aluminum foil. This is to prevent conflict with the Phantom's electronics from any electromagnetic emissions from the GoPro -- and at least one YouTube video demonstrates how interference can degrade the GPS lock-on. I've ordered copper foil to shield my GoPro, just-in-case. I wonder what others think of this? Should I use the leftover copper foil to line my baseball cap? :?
