Hello.
Some days ago, right after the last firmware update (maybe it was a coincidence), i had my first spark crash... luckily with no damages!
During the fligt, i've noticed that spark was always drifting and because of that i decided to return home. When it was 10 meters away from the balcony, spark started to flight on is own straight to my building... my only reaction was to try to get him up. I then hear some crash noise and noticed spark was laying in the roof of the building.
Can someone help understanding what happened? Here are the notifications (retrieved from the flight log, via airdata.com):
