I just purchased my P2v+ and it should be version 3. I am a bit concerned about getting a fly away so I am thinking about purchasing a gps tracker. Can anyone make any recommendations? or do I even really need one, as this post looks like it is now built into the quad. http://droneflyers.com/talk/threads/sma ... acker.516/ scroll down to the last post and you can see what I am referring to.
