I got my 3DRobotics IRIS a week ago. I've crashed it 3 times already,gone through 4 replacement propellers, and busted my gimbal. None of my incidents were due to a motor failing, I'm just a horrible pilot. Yesterday evening while flying with the kids, we got too high and the wind drifted it down the neighborhood. I switched it into "return to base" mode and it returned itself into an avocado tree.
I guess what I'm saying is: this software looks really cool but I doubt it will solve my current issues :)
