Just a few basic questions. First, will the Phantom 3 fly beyond its battery? In other words, if I set a waypoint mission and battery gets to low to complete, will the bird initiate an over-ride and return home before battery depletion? Second, say I have waypoint 1 at 30 M altitude and waypoint 2 at 60 M altitude. when going from point 1 to 2, does the bird elevate from 30M to 60M first, then head over to point 2 or is the altitude increase gradual between the points.
