Finally I have solved my problems with the quad turning left and right without touching yaw stick... Don't know if the key is latest ACM versions or the fact that I mount the APM/IMU over foam to reduce vibrations... in any case, now I can abuse of pitch/roll sticks and yaw is rock steady!
Unfortunately, I have a new problem :(
I can yaw to the right (although very, very lazy) and when I release the stick the quad stops the turn but when I yaw to the left (and release the stick) the quad spins but it does not stop!!
I tried with YAW_OPTION = 0 and 1, and also STAB_YAW_P between 0.3 - 0.7 without success.
I attach the log, where you can see four attempts to yaw to the right (the first two were not able to produce a real movement), a first yaw to the left that worked ok and a second yaw to the left that produces a not stop spin (more than 360º) until I have to take off!
Hope that someone can have a look at the log!

I will check again all the structure.
Maybe you could add some guidance to the troubleshoot section of the wiki regarding the logs. For instance, howto check if your frame is well balanced from the logs?
Everyone should learn howto to debug a copter based on a log.
Thanks.

I don't know if I would be able to distinguish if the arm is twisted 1 or 2 degrees.
Any trick to check it with accuracy?
Did you check that all motors are horizontal ?
