I was flying my tri for about ten minuten and suddenly he turns upsitedown and crash with full speed in to THE ground. Does anyone knows what can happend? I don't use any connectors on the end of the arms to my motors. So à bad connection is not the problem I think. I also watched the log but I can not see any big issue. I wil send the log in my next post. One motor was very hot when I picked my tri from the ground. I don't know if he was hot also in flight or only when he was on the ground trying to turn. Thanks in advance for eny answer.
