Other than iPhone Android connectivity, the Flamewheels will do what the P2V does only much better (zenmuse gimbal). Total cost is a bit higher for the 550 but the capability is there - more than in the P2 (or P2V) if you believe all the posts. I tend to believe them - I bought one a short while ago and I'm waiting for it to arrive. It's flight time is lower but the flexibility and extensibility of the design means it can do a lot more (lots more lift - it could lift a Phantom - it is a hex layout) and the batteries are cheaper. Looks like a homebrew but no one can see that issue in the air.
You can buy them read-to-fly from helipal for about $1700 for everything included except the camera (osd, FPV), assembled and delivered. You can also buy kits and assemble them yourself (which would be cheaper than a P2V).
