If you set your flight limits to 75 feet you’ll probably be able to find and retrieve your P2V+ if it gets away from you. Also, if your P2V+ is behaving erratically, turn your camera off ASAP. It will save battery life and may increase GPS signal strength.  

I would like to know how to do this.

Jeff, fire up your Assistant software on your pc. You'll be able to limit your copter's altitude and its lateral distance away from you, i.e. "home".
