a couple time ago i suspected having a issue with one motor, but after cleaning everything and even switch it from position everything was good. About CCW not sure, will test if it happens on both direction but i believe so. Regarding the gains i´m using the naza recommended ones, still haven´t played with other values. This weekend i will play a bit with the yaw one to see if helps, also i will place the batteries under the frame and not above (as it is now).
Will share results.
