R.I.P. Spark. Spark had another unexpected loss of altitude, this time with DJI Go 4 in FPV mode. I was hovering at about 100’, just above tree level. I decided to climb and pushed left stick up. Spark began to descend!! I was only 150’ away from the bird and I applied full back right stick. As spark was coming toward me and still descending it caught in a tree and tumbled into the woods. Unfortunately the area it fell into is covered in wild multi-flora rose bushes. Very painful stickers. So it may be winter before I can attempt to retrieve it. Is there data on my iPhone that might be of interest?
