Dear KlooGee, thank you for your feedback, since I am not familiar with that procedure ( it was the first flight of my drone and now is damaged) I will try to find the flight documents, because honestly speaking I do not know where I have to search for them..As soon as I can upload them i will follow your instructions because it is very important for my to understand why i couldn't control my drone and finally that heats on a wall (. Regarding the landing surface it was clean it was flat and another important factor it was night, without winds. From my point of view the weather conditions were perfect and since the moment that I lost the control of the drone it was flighing up to 4m. far away from me and the remote control.
The directions for getting your logs is on the page I provided.
Night time is a tough time to fly, especially for your first flight. Drones have 3 systems that basically help them understand where they are (GPS, Compass, Vision System). If any of them aren't able to do their jobs well, the risk of a bad outcome significantly increases.
GPS - the drone needs to have a clear view to the sky and quite often can take a minute or longer the first time you turn it on in order for it to find the satellites and lock into its location. If you took off without letting a good GPS location get locked in, this could have contributed to the behavior you saw.
Compass - the drone uses the compass to know which direction it is facing and compares that to the accelerators to determine if it is turning or not. If your compass was experiencing magnetic interference from something magnetic nearby (such as rebar in a concrete slab), this could have contributed to the behavior you saw.
Vision System: The Mavic Mini has downward facing cameras that it uses to help it know how far it is off the ground when it is close the ground. It also uses it to help know if it is moving by tracking objects underneath it. If it was dark out, the vision system would not have been able to function and do its job and can contribute to negative outcomes, especially if the GPS or Compass also was not in ideal conditions.
