Hexa flies fine for 10 minutes then sets off like a bat out of hell, cartwheels - one plastic nut broken

Hello!

I was flying my 3DR hexacopter for the second time today. All went fine, loiter, circle, stabilize, alt hold etc. After 10 minutes I was loitering at 1-2 meters (3-6 feet) when all of a sudden the copter took off at 9-10 m/sec and cartwheeled into the ground. From start to crash it took 4-5 sec. The only thing that broke was a spacer between one of the legs (as far as i have been able to ascertain)

I have a 5000  mAh 3S lipo and 6 880 kv motors.

My question: Any guess as to what happened? Brownout? Lipo was fully charged. (I have a voltage warning thingy in the mail.)

I attach the telemetry log. Crash.tlog The fun begins at around 590 secs.

How come the lipo voltage is not logged?

Thx in advance,

/RS

    I would estimate that a 5000 mah battery would last about 10 minutes on that frame, or about 590 seconds. Did you check your battery after the flight?
