Thanks!VPS is only effective when your Phantom is between 1 to 9.8 ft in the air. I don't know about you, but my Phantom is rarely flying at that altitude when I'm outdoors. Also, some people have experienced some instability when taking off and/or landing with VPS enabled. Those are critical times for accuracy, so it would be best to fly manually so you're not at the mercy of a computer that might override what you're trying to do.
