I used Litchi with a Spark and was initially very impressed with the ability to use waypoints. I ran a few small missions with the drone in sight and everything did as it was supposed to. I then planned a longer mission but the drone lost signal and RTH. There is an option in Litchi that allows for the drone to continue with a waypoint mission when signal is lost, i.e. it will run the mission and then RTH if this is what you have selected to occur at the end of the mission. I tested this on a short in sight mission by launching the drone and then turning off the Remote Controller. The Spark performed the mission flawlessly and RTH at the end, even with the Controller turned off. OK, so I sent it on a longer mission, well within the drones capabilities but I knew that signal loss would occur, the drone took off and followed the waypoints and went out of sight until i received a warning that signal loss had occurred. This is the last that I saw of it, never returned, even low battery failsafe did not work. My advice is be very cautious when using third party apps like Litchi, advice that is frequently given out by the DJI moderators in this forum.
On your return, either by mission design or RTH, if the uav is flying against the wind, it may not be able to return, attempting to return against the wind until it reaches critical battery and then lands. Flying out against the wind and returning with the wind is doubly important in long flights and stiff winds. Just a thought. |
