Hex+ starts to Yaw, failed to take off

Hello guys,

My craft flew okay days ago. No changes were applied and and mechanical structure was not damage since the last flight. Today, I have the problem that it can not take off. Right at the moment, I input the throttle, it started to yaw.

It seems to me the servos out (motor 1 to motor 6) went wrong!

Hope you guys have some time to help me figuring out the problem.
Thanks in advance.

It was about the trim on channel 4 (Yaw) - trimmed by parameter RC4_TRIM, not the controller. I have no idea why it happened but as I claimed above, everything was the same (even the controller). Basically, it is solved!.
Thank you guys.
