I have had two GS flights, and both times, the phantom took off in an unexpected direction. How does one know which direction it will go? I couldn't get a "map" of where I was - only a GRID was displayed. Is there a way to get a map per se? At my home I get a map of my neighborhood, but where I went to fly (still lots of streets around) there were no streets on the GS display - just a grid ... ? Is there a user manual for GS on the iPad? Or detailed instructions on how to use all the capabilities therein?
