Hi, i've a problem and i need help. I've order the Nd filters for phantom 2 vision plus from phantomfilters.com. http://phantomfilters.bigcartel.com/product/nd-filter-set-for-dji-phantom2-vision I've recieved the pack, but the filters are more big, margins come out from the camera and explanations for installation refer to phantom 3. Can anyone tell me how to be installed? If you have photos is better? Thanks!
