I was flying today off Point Loma in San Diego (yes, my flight was legal), and decided to switch to sport mode to get it back more quickly. At that point, I got the dreaded “Aircraft is disconnected” notice. I tried switching back to regular mode, and no luck. Funny thing, the controller (not the DJI app) still showed my elevation and distance, but not all the info. The MP was out over the water, no more than 1000 feet away. Thankfully, it returned to home on auto without incident. Just wondering what I did, how it happened, and how I can prevent it.
