Welcome to the forum from Chicago the Windy City.
To help you from crashing your drone, would recommend reading the manual.
For instance, understanding the RTH (return home feature) it works very well.
But it can do unexpected things if your not sure how its supposed to work. There are many possible scenarios that could occur when RTH is initiated. Please carefully review the RTH section of your DJI manual so you fully understand what to expect.
I believe in prevention, rather then I don't know what happened? Why did my drone crash. The RTH feature is one of the most complex features of a DJI drone.
And, knowing what to do in a emergency situation. Have some sort of Check list what to do in a emergency situation. Fly Safe, be safe, and have fun.
