Hello Keith,
Well, could a servo worn-out in this little time?
I think I about 125 Flight in total on this servo. ( not even one year old )
I’ll try later to tighten them a little, and see what will happened.
And could you explain to me what a dead band is. (Means)
I think that it has to do with the range off the servo movement.
Regards,

Danny, How quickly they wear out will have a lot to do with how much vibration they are under, 125 flights seems a little low, but I'd say it's not out of the question that they could have worn to the point you have oscillation.
Has this servo been in this plane for 125 flights? If so, how long has it been oscillating?
The dead band is the neutral area when the servo is centered. The servo is constantly trying to keep the rudder from blowing right or left and the dead band is the area that the servo considers the center. So if the servo has a dead band that is too narrow it will constantly be fighting itself moving the rudder back and forth trying to hit that center point. Horizon can adjust this dead band when it is too tight.
Troy Newman has some good threads on JR servo life and repair as it relates to pattern planes here on RCU. You might try doing some searches to see if you can find them.
