"Looks like a radio failure to me.  If you plot the Pilot's input for roll, pitch, yaw and throttle that they stop updating at about 2700.  Generally I'd recommend setting up and testing the throttle failsafe (instructions here)…"

"Thanks Graham - yes, after approx 2715 there is a sustained roll and pitch input that we can't figure out. I'll ask him to post a tlog - hopefully there is one."

"Just had a quick look and something that stood out for me from the log is that roll and pitch input seem to be way off for a period before the crash. All is good until line 2730 then everything offsets by a substantial amount. This only happens to…"

Copter: 3.0.1: Near flyaway, not sure why

Hi Guys, Need some help here...One of the guys at our club had a near flyaway today - from his account his hex was in ALT_HOLD when he lost cyclic control and it started to fly away. Fortunately the area was surrounded by trees, one of which caught the runaway.Attached is his dataflash log - seems the runaway started at approx 2715.At this point ATT.RollIn goes to -7.8 and ATT.PitchIn to -12.2. The copter accelerates to approx 10m/s (GPS.Spd) before the tree steps in.Need a more experienced set…See More

"Try adding about %30 expo on your RUDD channel (on the radio) - this will soften the stick response close to center stick."
