Yes, you can export as a KLM file and import it to Google Earth. This will give you a good idea of the accuracy of your Geotags. My partner and I have had great success with the Inspire using Pix4D and MapsMadeEasy.
I am having the same issue with my slave controller. I am running the updated firmware with two iPad Mini 2 for the master and slave remote. The master signal is strong barely a flicker. The slave losses connection quite frequently. I have an inquiry with DJI. Haven't heard anything yet.
The 360 degree camera and two operators separates the Inspire from the Phantom 3. I have both platforms and they are completely different from one another.
