I recently got a Sky Viper Journey, and I am trying to plan a “simple” mission with QGroundControl v 4.1.1 for Android. I define Takeoff, followed by three waypoints in a polygonal pattern, then RTL. The points are spaced by roughly 50 meters from one another. When I execute the mission with my Sky Viper it takes off and flies for about 15 seconds to the first waypoint, then immediately executes RTL. I’ve tried this three times with the same result. I am using the Viper’s factory-installed firmware. How to analyze this problem? I have tools mavlogdump and online UAV Log Viewer. Has anyone successfully defined and executed this kind of mission with QGroundControl and Sky Viper Journey?
