It's on the starboard side of the drone under a flap. It's right next to the Micro SD Card. If you're using your controller and not a tablet or smartphone, then you're flying it RC. RC is great, but it's really Line of Sight. Straight out over the ocean, I can go a couple of miles before I lose signal. In my tree filled neighborhood, I can only get about a half mile. Obstacles severely limit the distance you can go. Trees, houses, cars and anything else that can block your signal will reduce the distance. Height helps a lot. I can go a lot further if I go high because I am eliminating a lot of the obstacles.
