Warning for those using automated flight modes. This was tested by a user on the RCGroup forum and confirmed by Blade Strike. With both the DJI GO APP and the SDK Apps (LITCHI), the failsafe mechanism is to LAND at the current location once battery reaches the lower critical threshold. http://www.rcgroups.com/forums/showpost.php?p=32653595&postcount=37041 For example, if you ORBIT and lose connection, it will continue to orbit until battery reaches the low level at which point it will LAND, rather than RTH. This occurs with HOME LOCK as well. if you lose connection, it will hover until low battery and just LAND, not RTH. For Waypoints, if connection is lost, it will finish the mission and perform the action assigned (hover, return to first point, land) during the pre-mission planning. If you chose HOVER, it will hover until low battery and LAND. He has not tested Follow-Me, so not exactly sure what the behavior is yet.
