Ah,jrh75. I took Spark out today to try ELIT but as it turned out after launching I spotted a couple of deer and burned up 2 batteries taking pictures straight on and overhead. Deer are very unusual in this park but I did try to run ELIT. I noted a initial message saying DJI Go4 must first be launched contrary to instructions. I noted a new icon on my iPad mini 4 but I cannot say I fully used it yet. A question,: can you use both Course and Home lock on the same flight? I look forward to really trying it.
