"I didn't mean to mention every single quadcopter out there in my list. Just wanted a few examples in each category. The Blade 350 is largely a Phantom 2 clone, so I didn't want to mention 2 very-similar quads. As for return to home, you can do this in the Phantom by flipping to failsafe mode (if you have enabled Naza in the software). As for the AR Drone, I feel like that's a bit too much of a toy and didn't want to mention it" - Paul Stamatiou
