I flew a 2 battery survey yesterday afternoon on the new software/firmware with an E90. No interruption or freezes of DataPilot. I did have a "loss of remote control" warning, but I had all telemetry and control when landing. The screen showed the survey pattern and picture dots throughout. I did an RTL at 27% and resumed after the battery change without difficulty. I will try another survey in the next 1-2 days if the weather cooperates. Thus far seems to be a much needed improvement.
