Hey guys - I think I mentioned this in another post - but I really saw a stark example this weekend - wondering if any of you are seeing it as well. I have an iPad GS latest firmware on everything with a Phantom 2 Zenmuse setup with go-pro. When I initially get communication set up with the Phantom in it's take-off position it reads an altitude of about 10 ft (sitting on the ground) THEN - I take off and fly it through several waypoints and land... when I look at my GS getting ready for the second mission - the altitude now reads ~30 ft... sitting in the same spot as before. I believe this is what caused my crazy flight about 8 days ago (setting it for 30 feet and it flew closer to 2 to 3 ft off the ground) Has anyone else seen this? The GS reads one altitude on the ground for the first flight and then a second altitude on the ground for subsequent flights? (on more piece of info - both flights I had about 12 satellites - don't know if that matters).
