I think my APM just died midflight of course leading to a crash.

I have attached the tlog. The flight does not start till 80% through the log.

I took off in manual switched to loiter then to auto for a 3 waypoint mission.

The plane flew the mission then after it had finished I flick the switch to manual and then immediately after to stablize.

I seemed to have no control after switching to manual and the plane was descending under power.

It crashed not far from me and when I walked over the ailerons were twitching. I did not check the 3dr radio link before I unplugged the battery.

I wondered what had happened but thought the logs should tell me when I get home.

I cannot get any onboard logs because the USB connector was damaged in the crash.

I had a short extension cable plugged into the board and momentum is far stronger then solder joints.

So when I checked the tlog I notice that it just stops before the plane hit the ground (almost immediately after the switch to manual, does not record switch to stabilize).

Telemetry had been working fine so I assume the only reason the log would stop is if the APM crashed or rebooted. Either not a good scenario.

I am relieved it happened in the middle of the park rather than over the river.

It's and APM1 2560 with a meditek GPS and airspeed sensor. Both pitot tubes bent in the crash.

Anybody care to take a look at the tlog or offer any suggestions as to why the log would just stop mid air unless it was due to APM failure in mid air.

Just a reminder log does not really start until about 80%.

Oh and is there any good reason the CLI and log download does not work unless connect via USB??

In my case USB connector is had it but I can still communicate with the APM via the radio.
