This is a DJI crash warning for dji s800 drones and aerial Drones using the wookong m flight controller. a dji s800 wookong m flight controller, imu and gps can be heavy affected by electromagnetic interference as seen in this crash video, and will cause your dji s800 drone or any other drones that use the dji flight controller system to violently crash without warning and cause pilot to have complete loss of control which is very dangerous, another instance is the s800 "flip of death" although i think the s800 flip of death is related to poor gain adjustments to the UAV Flight Controller.
please watch this video and be careful when you fly your drone, quadcopter or any other aerial platform using dji wookong flight controllers. sometimes i really think just a simple quadcopter with a openpilot cc3d flight controller is more stable than the dji stuff, just my experience.
as in the case of FPV racing drones, they are very stable and crazy fast, or even DIY Drones.
