Supported of iPad Ground Station and PC Ground Station functions. When using iPad Ground Station, the BTU firmware should be upgrade to V18.104.22.168 or above. 2. Added Flight Limits functions, including Max Height and Max Radius limits. 3. Added LED indicators warning, if non-DJI smart battery is detected, the LED flight indicators will be solid red. 4. Optimized compass calibration algorithm to increasing its resistance to interferences. 5. Improved battery level detecting methods to make low battery level warning more precise. 6. The maximum descending speed is limited to 3m/s. 7. Fixed the bouncing problems after landed. The question I have until I update is if the flight limits means it will know if I'm in the US and know that I'm not allowed higher than 400 ft and stop me. The "non-DJI smart battery" thing is neat. Does that mean someone is making cheaper smart batteries that I could buy instead of buying $150 ones? At first I thought this was to prevent people from putting the Nava 2 in the Phantom and using any battery but this isn't a firmware update for that naza. the compass swirl issue I've read that has bother many has been solved (and people debate on if they should update or not) The speed decreasing descent is questionable, I wonder if 3m/s is slow enough that I could come straight down and avoid my prop wash. Or because people don't understand airflow and just come straight down all the time and then cry about the prop wash making their Phantom crash.
