When you hit the limits in beginner mode, the bird just won't go any farther/higher. It's not going to land. When you set RTH, remember that all heights are referenced from the Homepoint/takeoff location. So make sure that you take into account any changes in ground elevation in the area. For example, say the trees in the area are 75 ft tall. You might consider that a RTH height of 100 ft (RTH is set in meters, so 30 meters) would clear the tree. Ifthe ground rises up near you by 50, the top of that same tree would now be 125 ft (40 m) above the HP and a 30 m RTH could cause the bird to fly right into the tree. And remember, phantoms are pretty good about holding a height, but the altimeter isn't calibrated. Give yourself a bit of safety margin. I've flown up to a height that I thought was above the trees or obstacles and then slowly panned around looking for anything as high or higher than me in the area where I wanted to flyjust to make sure
