And it's this that can be the big risk for a newbie ......I typically power on my drone and set it down somewhere clear of ... magnetic interference
-If you don't know that steel rebars inside reinforced concrete creates magnetic interference
-If you don't know that a rock boulder can contain ferrous material
-If you think it's risk free to place the craft on a wooden deck during power on (& don't think about that nail close to the craft)
You might then on height be in for a big surprise ...
The best is to always keep the craft as far away as possible from everything during the powering on sequence ... & then check the result on the app map.
