I was in beautiful Sedona, AZ and took the drone to take some panaramas after a hike. I know there is no logistical problems with taking the drone over the edge and even taking it down. However I left that day with a little uneasiness. The windws were between 0 and 10mph so nothing major. I took off several times with full gps and about 30 feet from the edge. Coming close to the edge, the drone definitely had a hard time with smooth flight and would bounce around. I turned off VPS and it definitely seemed to make it better (Placebo maybe though?). I'm assuming this instability was from crosswinds going up and down the edge? When I had my wife try to catch the drone about 20ft from the edge, we were actually having a very hard time. It's movements were too choppy. At 30ft from the edge it was all good. I did calibrate the compass there. Maybe the ground there had some magnetic effect? I flew maybe 20-30 feet above the ground. I know if I took it 200ft up none of this would happen. Also once I started getting farther from any edge and in the middle of the canyon it was all good. However this behavior made me very nervous to fly it in that area and I actually only went about 400 ft away and wasn't confident enough to go down into the canyon. Anyone else experience this?
