I have had my Mavic 2 Zoom for about 6 months. I may go as much as 2 weeks between flights because of work or the weather.Ah, wow, never had that before. Many thanks, just learnt something new.
I do a compass calibration each time I change flying locations. some people say it's not needed but I figure the time I spend doing this is time well spent. It's kinda like a check list I do.
I did get to close to a cell phone tower once but I was getting choppy video. My display said lost of signal... return to home.
At this time I pushed the joystick forward to gain height and re-acquired signal. After then I headed for home.
Those cell towers are broadcasting strong signals. Now the 5G poles they are putting around Houston present another problem.
