New to the hobby! I live in NM and we have some really cool caprock areas were the ground will suddenly drop off like a cliff for several hundred feet. These caps are out in the middle of nowhere a hundred miles from civilization. I thought they might make some cool videos, but I'm wondering, will the Phantom go over the side of the cliff and then immediately drop itself back down to 400' relative to the new terrain? I'm afraid I would have a big problem flying the thing back up to where I started.
