UAVs are precision electronic products that, once infiltrated into the interior, can corrode internal electronic components. After flying in wet weather, in addition to simple wiping, dry dehumidification should be done.
The drone can be placed in an electronic moisture-proof box, or the drone and desiccant can be placed in a sealed box for drying and maintenance.
The impact of sand and dust on drones is also very large, especially for motors and other equipment. Take off from sand or gravel ground as much as possible. After flying in a dusty environment, it should be cleaned up in time.
Keep away from magnetic objects
If the drone is in a strong magnetic field, it will cause the compass to be abnormal. When not using the drone for a long time, keep it away from the strong magnetic field.
