There's no way a <900g drone can kill anyone, no one in the entire world has died by a drone accident and in the entire history of RC aviation only 2 people have died, one with an RC copter and the other by an RC plane on a show... People get killed in car accidents, not in drone accidents, and everyone is still driving despite that.
That being said, let's get back to the topic.
In the log it can be seen that when RTH was engaged the drone was at 80 meters from the hompoint, so the drone started to climb to the RTH altitude that was set at 90m. While it was climbing to the RTH alt you pulled down the stick at 71m and cancelled the RTH and regained control over the drone. After that you flew it backwards, descended to 37m and then autolanding was engaged with 12% battery left. It didn't find a proper place to land, and you manually performed a 360º rotation and the flew it to the lake where sadly the battery hit 0%, and it entered the forced landing mode, and at that point the pilot has no control over it.
While the drone was trying to land on the ground it was at low altitude, so the OA may be interfering with the control of the drone, but moving to the water was a bad decision.
When auto landing is engaged the drone starts descending, but you can manually pull up and still get control over it, so you should have puledl up a bit and then let it land on the road, or just fly back home, as it was only 100m away.
I see no deviations in the batteries (brand new, only 1 charge), no problems in the control, GPS, compass, no signal loss and no hardware or software errors in that flight. When the Flyapp crashes midflight, for example, logs are usually split in two files. All that can be seen if you upload the log to UAV Airdata.
... happens from time to time, I have 470h of flight time and the other day I let the M3 go before motors were fully engaged while I was performing a takeoff from the hand, and it went down; it was not damaged because engines still managed to do a bit of thrust before "landing" on the grass... blaming the hardware for an operator fault goes nowhere. DJI drones and soft are far from perfect, but most crashes are allways pilot related.
PS: And it took around 5 minutes to go from 40% to 20%, which is normal on the Air2S. |
