That I don't know. Which is wearing. Sounds like a good place to start.
Thanks

>    Another discussion about pull-pull systems. I use pull-pull on the rudder and compared to the elevator servo the rudder servo gets worn and loose at the top bearing much quicker than the elevator servo.The cables are not too tight and are setup correctly so far as ackerman is concerned.The rudder being much bigger than the elevators may cause some of this problem. More momentum...
