I updated the firmware. It's good a good GPS signal. I have it on beginners mod and did assisted take off, I did the proper calibration as well. First take off the drone spins out of control just one foot over in the air and chips it's propellers and ruins them and goes upside down. Second time I did it on grass and same thing. What am I doing wrong? Is it that there's too much electromagnetic activity around? Power lines too close? I'm worried I got a flawed drone.
