A bit more on the Phantom 3 Professional, I have had one for a few years now and it's just plain awesome, GPS stabilized, Return to home feature, Auto take off, speed up to 30 mph and one of the cool things is a follow me mode to where I connect it to my Nexus 7 which is GPS as well make a few changes on my controller and my drone will follow me! It's very stable in the air and there is so many things you can do with it. This thing boggles the mind for sure. I own 3 drones two with the build in camera the P3 and P3P and one other P3 with a gr Pro mount on it. I enjoy flying them all they all have a special use but the P3P it the one I use the most.
