Since I'm a Futaba user, I'll try to be nice about this. <VBG> I have an 
airplane set up with JR servos and I'm experiencing the classic "oscillating 
rudder" issue. There's a JR 8311 servo on the rudder and the cables aren't 
excessively tight. I remember hearing about this a while ago but I can't remember the 
solution. Any help would be appreciated.

John,
I don't know about 8311s, but I've had two 8411s do it, one brand new.  Some 
suggested an oring around the two pull pull cables, to apply a very slight 
drag..  I cured mine by going to an 8611.  Something in the 8411s is too tight in 
the feedback loop I guess.
