I bought a used Q500 4k. It had the quick start pamphlet and no other instructions. I watched several videos and thought I had a basic understanding of what to expect. I turned it on in the backyard and started it up. The grass was about 6 inches and touching the camera and so the camera could not turn. I thought I would just take it up about a foot and then set it down. It went up a foot but then it started bouncing two or three feet up and down and to the right and left. I hit the off button and it landed. I started it up again and this time it bounced up and down and came straight towards me real fast. It bounced hit the ground flipped and broke all the propellers. Is this normal of what to expect for the first 15 seconds of flight? I had let it set about 10 minutes before taking off to prepare myself and to let it find satellites.
