Just had a text from a work colleague who has just had a nasty "unknown" crash with his £2000 drone. Lost control of it and it decided to try and bury itself at full speed into the side of a ditch. Seen the video and it was not a pretty site. One thing he did mention was that he has found out he was flying when this site indicated not to because of solar weather: http://www.multirotoruk.co.uk/solar-weather Anyway, it isn't just Phantoms that this happens to !!!
