I have a few questions guys and some help would be greatly appreciated. Currently I have a P2+ with GoPro Hero 4 Black and Zenmuse gimble. I want to enable NAZA M. However, from what I have read from the manual which is not exactly forthcoming in this information. Do I need to install the NAZAM V2 hardware, or is this an upgraded version of NAZA? Second, I have been having a strange issue with maintaining controller link with my Phantom. This problem is intermittent in the most aggravating way. I have had numerous flights and have gone 3 hours without a problem. Then I will hit problems where i cannot go beyond 20 meters before failsafe engages. This will continue and then go away again in a seemingly random fashion. Any help would be greatly appreciated thank you for your time and consideration.
