Hi, a couple of quick tests with iOs Beta 1.5 on an ipad mini 4 with a phantom 4. Two days ago I found the application working perfectly but only had a few minutes and didn't record anything. Today I went to do more complete tests of the rails function but I found the stick controls way too sensitive to fly safely. Indeed, I thought that I was using the sports mode because the pitch and the speed of the drone was equivalent of what you get in that mode. But no, I was using P mode. I tried going back to dji go and again to vertical and it was reproducible: vertical on p mode behaved like S mode and back to djiGO it was normal. Other than the fascinating possibility of flying at S mode speeds with colision detection on (I tested and it worked) this was odd and disturbing behaviour, quite difficult to do any shooting.
The funny thing is that the day before yesterday I didn't notice this behavior, and I have not changed anything that I am aware. The only difference is that I flew one battery using Flight Logic's Autopilot prior to testing with VS.
Will continue testing, please let me know if there is something that you want me to do in order to help debugging.
