Plans? Did you mean to say Planes? Listen, if you're not going to be helpful...

Joe, I'm trying to set this 55% up and for the life of me I can't get geometry right on the rudder I've moved center point all over and still have 1/4" or more throw one way than the other, thinking I put my rod through rudder in wrong place. Don't you have a Vid somewhere explaining proper linkage set up and control horn? Here' s Video of this beast....Thanks,Vann

Need more details on what you mean by 1/4" more throw. Did you attach a video? I don't see it.

If you're talking about a bolt through the rudder... ain't no wrong place. Offset, like greed, is good. haha But, if it is pull/pull you might need one of these to get the non-pulling cable to neither get tight, nor slack:

Joe, it's push pull w 3 servo's in the tail, evidently my vid never loaded, I'll try again tonight. Thanks for the help... Thanks, Vann

You have to shorten or lengthen the rod till it throws the same either way.

I am trying to get rudder to move same degrees in each direction and ultimately servo do the same thing, so I can match the other two servo's to do the same and be linear. But to get the rudder to move same degrees, I end up with travel 100 or so on one direction and say 130 the other direction. I was planning to use Dubro horns on all surfaces and get all these servo's working together BD not fight each other... Is there a formula for putting the 8/32 stud/ horn in the right place to line up correctly with servo? Thanks, Vann

I have gone from one extreme to other, I can't seem to make it happen..... Never had a problem on other planes( But never tried to get servo's linear as Joe's Vid's either..) maybe me stuuuupid, LoL

I havent read the whole thread. But have you checked to make sure your servo arm is traveling the same both directions? End points and sub trim set to zero?
