Okay, so I want to setup a mission to survey a pretty large area using my scratchbuilt frame(average flight time around 12 minutes). The flight distance is 7.3km. Is there a feature anywhere that will tell me the estimated mission time? How about what happens if the time is longer than my battery life, is there a way to change batteries and reset the mission/resume from where it left off?
I realize the default waypoint speed is 500cm/s, can I just interpolate a mission time based on that? If so what can I do for resuming a mission once I change batteries?
