[NSRCA-discussion] Servicing Servos

[Jon Lowe]

I have to have aileron pots changed after 150 to 200 flights since I switched to YS from an OS 1.60.  Running DS9411sa's.  I get noticeable hesitation in movement around neutral.  The servo acts like it is stuttering.  I generally change aileron servos for ones with fresh pots right before the Nats.  I like the 9411's in all other respects, and I suspect that the pots wear because they are driven directly from the output shaft, rather than indirectly, plus the YS shakes the bejesus out of the ailerons.  The DS3421's I use on elevators never seem to wear out pots, even though they are much smaller and are also direct drive.

I assume the number changes for Glow vs Electric?  If so, isthat 100-200 typical for Glow or E?  And what should we expect from the other?

Thanks Tony.
  
  
  
 
  
  
  
Is the Pot replacement the only work needed to recover the  performance and give another 100-200 flights?

  I do a lot of competition pattern servos here at Radio South.  Most of  the time, you will be able to get 100-200 flights on servos, however there  are some that say they can feel degradation of centering in as few a 30  flights.  Most of the time, replacing a pot will cost you around $20 per  servo.

Generally, are people servicing their servos? How often (for glow    powered airplanes) and does the service correct chatter about the centre?
    
    
    
 
    
    
    
Where is a good place to send Futaba Servos and what's the typical    cost and turn around time?
    
    
    
 
    
    
    
Thanks
