Lost my drone

Sparky786 · Dec 31, 2017

Hi guys, after flying for couple of months lost my drone.
Having 60% still remaining it decided to land, after taking controll making it come to home point it decided to drift and i lost signal. It was only 200m away frm me but i could not gain controll.
I tried to find the TXT file but i cant seem to find it..should the file be on my flight record?
Thank you

Restart your Android device and check for the flight log then.

This happened to my mates mav. We found it by going into find my drone. But looking around at the gps spot it told us to go approx 500mtrs away we couldn't find it. So looking at how high it was at last info I decided to continue going in general direction and found it a further 200mtrs away in someone's front yard. Sorry to here about ur. Hope this info may help someone

Well looking at the flight log it looks like it has indeed landed safely around about 40 Rotherhithe St.
That is where I would go and start making enquiries. It might even be on a rooftop or up in a tree in that vicinity.

It took you 54% to get as high and as far as you did and it initiated RTH AT 46% so theoretically your remaining power was insufficient to RTH
The biggest mistake in this is your inexperience I'm afraid..... At 25% power it initiated Auto landing you could have cancelled this and flew it closer home as much as the remaining battery would have allowed.
It acted correctly all the way it was returning to home like it should but due to the distance and height you flew it to it hit the low battery which must be set to 25% in your parameters.
Also (And I do apologise as I am in no way trying to tell you how to fly) The UK height limit for flying a drone is 400ft.... You can be prosecuted for anything above this.....
Hope this helps.... So my opinion is Pilot Error.....
