Crash ArduCopter 4.0.7 (log attached)

Hello, I am not experienced in analyzing flight logs, can anyone help me figure out what went wrong?
My quadcopter armed in stabilize mode and it initially went straight up as I raised the thrust (as expected) but then I lowered the thrust and it rolled to the right and down and crashed. I didn’t touch the roll/pitch stick. This same thing happened 3 times. Thanks a lot for your help guys!

The graph shows that a roll signal was received from the control equipment. you also have a huge vibration, about 50 points. how long did the flight last? three seconds?
