Crash with x6

Hey there,

I’ve build a Hexacopter just for trying out the Pixhawk 2
I’ve used the following configuration:

6x KingKong 2204 2300KV
BLHeli 12A ESC
I know it is the wrong motor but I used it for testing only.
2x 2200mA Turnigy 3S Parallel 40C-80C
6" Props

My Copter was Falling out of the sky without any reason.
The LiPos where discharged by 500ma each.

Here is my Log:

Please help me finding the error.
