Hi All I have the GS set up and running on my iPad but I have yet to fly a mission with it for real. A couple of questions. 1) You have to have the Phantom live and remote live and GS live to set up a route and fly it in the simulation mode but can you run it indoors or does the Phantom have to be outside and have full GPS coverage etc etc. I have had varying results. 2) Why does it go astray in the sim mode? For example I built a route and set it running and it got to point 4 and hunted around for several minutes before it was able to and and fly the route to point 5. In sim mode I would have thought it would have just traced the route since its just virtually flying it.
