Just updated my Litchi app on IOS and noticed in the release notes that it has a couple of new features - RTH/Land button and Find My Aircraft. I checked after my update and indeed the Find my Aircraft is there now. Haven't been able to fly lately as it has been too windy but I am hoping there is now a RTH button available for the P3S. Won't know until I can fly because right now it only has the takeoff button. I'm assuming once the craft is in the air and far enough away the land button will become RTH. If this is so then that is a long awaited addition especially on a P3S. DJI GO has always had the onscreen RTH button but not Litchi. I prefer Litchi and use it 99.9% of the time to fly my P3S. Maybe tomorrow I'll get a chance to confirm whether or not there is now a RTH button since it is supposed to be less windy.
