My drone is back to it's old tricks!! this time crashing twice in the same afternoon!! the first crash was in to a tree!! I was very lucky not to have received any damage and even more fortunate not to of hit something or someone!! After the usual configuration of controller and drone (with full gps) as soon as it took off i had no control of the drone at all!!The second crash again after i calibrated and did the gps dance etc i decided to take off manually!! as soon as the drone left the ground she was gone! once again i had no control over the drone she spiraled around me at speed and then smashed in to a steel post completely killing the quad copter!! Friday afternoon she flew perfectly, Saturday afternoon she killed herself!! that is three crashes in 9 flights!! one minute she is fine the next minute she is totally uncontrollable!!! i have written to the company i bought it from asking now for a full refund as i am not prepared to pay for repairs again and i will never fly this drone again!! it will end up killing someone!!My brother has an identical drone to me and his flies perfectly, he has had not one issue with it and he was also flying in the same place as me yesterday
