Although the reports are specific to the DJI Matrice 200 series there is considerable data present that should be of interest to anyone that flies quads, and those that want to fly in the rain.
For DJI users, the reported number of failed motors or ESC's with the Matrice 200 is something to be aware of. The number of battery firmware issues is also quite serious.
