I recently bought a Phantom Vision 2+, so I'm very new to flying. I've made a couple of flights so far. All settings are as they would be right out of the box. I'm wondering if I take off from a spot, then either walk or ride as I fly. Will it basically have unlimited distance as long as I stay near within the stock controller range? Or is it only limited to a certain distance from its initial take off point? Hope my questioning is clear. Thanks for any help!
