Hi, our quadcopter uses a Pixhawk Cube with a Here2 GPS, and an Odroid XU4 onboard. We are having quite a few crashes where the copter starts acting weird (see video), and crashes. We’ve done calibration before every flight and Mission Planner shows no warnings. I’ve attached the logs for the latest flight (we first did a brief takeoff and land, and the second takeoff was the one where it crashed). Any help diagnosing would be appreciated.
