[QUOTE="ol' Sparky, post: 113821, member: 16402"] I've had that happen a couple of times. Both times at about 60 feet up and 600 out. It lost connection and satellites, went into ATTI mode. First time it took off away from me, but regained signal after 70 or eighty feet and responded to the controller. I think it may have had to do with the phone I was using being almost dead. Controller was charging it, but was still slowly dying. It might have tried to shut down apps to save it's battery and lost connection. Second time same situation near the same spot. This time it flew toward me and regaind signal/control about a hundred feet out. Later checked log and found It showed massive IMU and compass errors. Recalibrated both and later found that one of the prop tabs had broken off and am thinking there may have been excessive vibration that caused it. Lucky it didn't fail and drop out of the sky. Now I ALWAYS check my props have both tabs and are secure before a session. I think the point is...there's usually an explanation for a fly-away other than "it just took off on me", though I have no doubt that HAS happened. Now I don't fly unless all batteries are fully charged and a proper pre-flight. Haven't had a problem since. Knock on wood. [/QUOTE]
