Elev. Pull pull Question

[Rcmaster199 at aol.com]

Bobby, 
 
Ron Ellis has written a very comprehensive procedure in setting up  pull-pull 
systems. You would find it in his website at Grotto2PatternPage. 
 
In your particular set-up, it sounds like the horn length on the one that  
travels too far is a  little short, or the geometry is off slightly. I am  
assuming that you are using one elevator servo to drive both halves.
 
In regard to setting up the cable tensions, a good trick I picked up  from 
Ron's method was the use of rubber bands to simulate flight load. Slip the  
bands over the horns and apply tension such that flight load may be simulated.  
This gives a pretty good in-flight approximation of surface track.
 
And one more thing: if you are using 6-32 bolts as horn material and you  
need to bend them, the easiest method I have found is a 1" length of aluminum  
threaded tubing from ACE Hardware. Makes an excellent lever and there's no need  
to scar the threads with pliers

May seem obvious, but I could use some help  here....setting up my 
Excelleron, centers are okay, cable tensions are pretty  close, centering is good.  Up 
elevator is fine, on Down elevator, ONE  elevator moves farther, but they track 
together except at the endpoint, as  close as I can tell.
 
Anyone have suggestions on how I'd fine tune this  out...??
Hope everyone had a great  T-day!!
