Looking at the data from my first flight today, it tracks the full flight, however towards the end of the flight as I was returning home, I tried to activate RTH instead of using fpv and it did nothing, no gps available even though precision landing was activated on initial take off, fortunately I was able to fly back in my general direction using fpv until I had good los and landed to change out for a new battery, from that point onward I’ve had no drone gps, it does drift a lot now after launching with no gps signal
