Is a smartphone required to control a DJI Phantom 2 Vision+? Not sure if this is on-topic here, as the official guidance seems a bit vague.

Anyways, I've got a relatively simple question.  I'm considering purchasing a Phantom 2 Vision+, but am a little unclear about what options there are in terms of controlling it.  Their website makes a big deal about being able to set waypoints (using an iPad/mobile app) and have the quadcopter operate as an autonomous drone.  And that's useful for certain things, but it seems like it would be more fun to control it directly by remote.  

Judging from the video here, it does appear that the quadcopter ships with a remote.  But it also looks like you're expected to stick an iPhone/smartphone onto the remote?  Is that a requirement or just an optional extra?  

Is it possible to fly the quadcopter without using a smartphone/mobile app (using just what's included in the box)?
I'm pretty sure it works without the smart phone. If I understand correctly, the smart phone app simply relays the imagery from the camera, which can be useful for navigating especially if you do not have a clear line of sight.
