I don't have an internal compass. Usually, when I'm flying, I have zero idea of which way North is.
I have a friend with an amazing internal compass. He could be in a winding cave and tell which way North is. It's bizarre.
I am most of the time relying on the compass - if I lose orientation relative to the drone, to get an idea of where the drone is . In default mode I think it is relative to the controller (you can switch it to drone perspective centric as well)...
Whenever I fly my drone, I lose sight of it.
It's not difficult to do. It's off-white and the sky can be off-white (cloudy) and all of a sudden it disappears. Happens all the time.
That's why I finally bought one when I did. I wanted some way...
