Hello:

I have a friend that is having some issues with a Naza V2. When hovering it slowly make Yaw, also when flying it go straight but makes ya while flyuing up to a point that is sometimes at 90 Degree.

Any recomendation or solution?

Does the RC been calibrated?
The Yaw channel is in mid while RC's idle?

Yes it is at middle, is like is yawing slowly without any input.

which flying drone do you use?
has the compass been calibrated?

Is a F550, the compass has been calibrated. I think the problem is one of the motor/ because when I make some inputs i hear a short winning noise is heard. Also one motor stops much more faster than the others

I've got the same problem, but changing motor (which stops faster then others) did't solve it.

I had this problem too. I'd used the ESCs on another multirotor with a diferent controller. The ESCs had been calibrated witht that controller. Ok, O had a couple of spares, exactly the same type, so I replaced a couple on the aircraft.
I fixed the problem.  Maybe calibrating them all will fix the issue

If the yaw gain is to low it will do that  in order to get my F450 and F550 to fly straight I had to take the yaw gain up real high.. 170 on my F450 with the E305 propulsion system and my F550 with the E310 system up to 190..  But all my other basic gains are fine at their default settings.  I also had to set my attitude gains up quite high to get the stick response I liked, They are set at 170 on both copters but were fine at 120 when I had the original E300 propulsion system on them..  So the more efficient propulsion systems required higher attitude gains...   No matter which propulsion system though I needed high yaw gains to keep the copters straight while ascending and mainly descending and when I would stop or go..  They didn't spin in complete circles but they would turn 45 degrees or so  and I would have to keep using my stick to straighten them back out..
