I was flying the drone last week when it lost signal with the remote control, I was only 150 yards from my remote controller at the time and have flown the exact same route several times. It lost signal and I waited as I thought it would just fly back home but it hovered and then dropped to the floor. I contacted online support and they gave me an RMA number and I boxed it up and sent it in after being told they will repair it. Yesterday they now inform me that the item was crashed and I have to pay £150 repair bill which I know isn't a lot of money but its the point. It was NOT crashed, it dropped from the sky, to me a crash is hitting something whilst going forward, sideways or backwards but not when it loses signal and falls to the ground. To me this is a fault beyond my control. Is this the normal way DJI go about such issues ?
