Arducopter 4.0.5 Sould i worry for the motor No4

I allready build a Quad with Kakute 1.5. When i look the Logs in RCIN i saw this difference in motor No4 compare to athers motors. Sould i worry about it? The quad flyes beautifull and lock in the air. I attach fotos from RCIN and RCOUT.

RCIN 4 is normally YAW control. Just means you never commanded it yaw at full speed the other way.

And the other RCINs are Aileron, Elevator, and Throttle.

@Stamatis: If anything either the aircraft is not balanced in roll and pitch, or there is some physical misalignment between the thrust line of motors #4 and the aircraft frame.
