I just tried to fly a perimeter flight of my subdivision.
Calculated flight time 11 min, distance 2.1 miles. Cruse speed 15 mph.
There is a little bit of wind, but not too much.
Drone had 98% battery at start of mission.
I lost connection after a couple of minutes. The drone was maybe 1/5 of the way around the circle. At 7 minutes, I heard the drone coming over my house, and my controller started beeping. There was a RTH alert for low battery... I didn't touch it, it reported about 20% battery. The drone flew to the home point and began to land, the controller blaring the whole time.
Once the drone landed, the battery was <10%
Plugged the drone into the Mac to d/l the video and see what was up. The drone made it approximately 1/2 way through the mission and then turned straight for home.
Actual video length 7:29 take off to land. Battery left.. almost nothing.
I have Smart Return to Home enabled and battery set to 30%, but it would have had to start the trip back well before 30%, or it would have never made it.
I may try the same path again at 30MPH to see if it can get farther around, but it is quite scary to not have control of the drone for any length of time just hoping that Litchi gets it back.
This time it did.
