thanks guys this helped quite a bit! yeah I got no warning before taking off which is strange.
As I reflected a bit further ......
For quite some time I kept a cheap camping type compass in my go bag. I used it for two things.
1 If I am in a new area I like to place the bird pointing north by sight with the camping compass.....
I step a few feet behind it and place iPad or other device with mounted controller pointing north as well.
I step back again and eye ball the alignment of my lay out....sometimes I might go point the bird a degree or so either way....sometimes the controller / display.
Depending on the day I may go place compass in front of bird.....or behind the controller....
at. This time I go through start up sequence......let it stabilize.....then stand up with controller and see if all points north.....
im not sure the exact name but the positional indicator in DJI Go 4 shows bird pointing toward the N and the part that shows relation to controller.....
Rotate your body with controller left and right.....like you would if flying.....If all the positional indicators move like you feel they should and the N indicator stays put I feel pretty confidant I’ve done all I can do in a real world environment.
I don’t do this every flight.....maybe I should.
That was a whole lot more than you were asking but most of my flight time is from a 10 acre field that had a farm implement JUNK YARD on it for 50 years....I still find pieces of metal to this day....some of it buried just below the grass....that makes for some screwy errors....or indications of something is off on take off.
Yea....I got some experience with how a bit of metal can throw a UAV into a confused state.
Dont ignore your gut feeling about surroundings and any positional indicator behavior.
