This afternoon I went out to test the Litchi Photo and Interval and Timer settings on a waypoint mission. The Phantom flew the mission perfectly. However, when in the Litchi Timer mode, each time a photo was taken the Phantom would quickly (but very briefly) jerk backwards like it was putting on the brakes, though it continued moving forward with the mission. It was very unsettling to watch. Also, it did not take photos at regular intervals as set with the timer setting. Has anyone else experienced this?
