1. Should I turn off cell phone wifi/data/blutooth while flying? Is this a good practice assuming you have the map already loaded? Is the issue possible interference and not having someone call you in the middle of your flight (and cutting down # of running applications)? Airplane mode should be activated I assume as well. 2. I guess I will find out, but when you move the direction level forward, will the aircraft maintain altitude or do you need to correct for this? 3. Is the "distance away" metric the horizontal distance from you or the hypotenuse leg of the right triangle? 4. Is "altitude" measured from above home point, sea level, or ground level (which will change as you fly)? 5. Will be using a Galaxy S6. Anyone have any issues with this or recommendations? 6. How close to a body of water should I be before I start worrying about shutting off the visual positioning system (if that is necessary?). Planning on flying over water most of the time. 7. Realistic expectations for max distance (line of sight, no obstructions)? Lots of conflicting info out there... Thanks in advance!
