My new platinum basic kit arrived and I got it all updated. I launched it and it is pleasingly quiet. I have been flying my spark around for the last week and it sounds angry. You can still hear the platinum obviously but all the high pitched ringing and buzzing are gone. I am glad I return my regular mavic for the platinum. I did get one extra regular mavic battery for it since the platinum version is in short supply and the color goes well with the platinum.
