A couple days ago I replaces two arms, one attached to motor 2 and the other to motor 4. Now when I lift off the ground in GPS mode it slowly turns (as if I'm applying rudder) clockwise. If I push the rudder left about 20% to compensate and hold it there it stops rotating. All other functions are normal, Aileron, Elevator, work normally. GPS hold works as well, as long as I keep the rudder pushed left a bit. I re-calibrated the GPS, this did not help. Any suggestions would be greatly appreciated.
Thanks,
Peter

Why are you asking questions about Naza-M in an Arducopter forum?
In general, the problem is likely because your props are not perfectly aligned for some reason, not perfectly vertical. This can often be worked around by increasing your Yaw Rate I and Imax, but I don't know if you can even do that with a Naza.
