Help.  The more I study the plans, the more confused I am.  The rudder cable outlet fairing has me stumped.



On the 601XL, 6-B-4 shows an 8mm x 20mm cutout for the rudder cable, right above the bottom longeron.  Then if you look at the drawing for the fairing (6-B-4-2) that would seem to put the cutout near the bottom of the cone-shaped exit tube.  Finally, the picture of the nylon fairlead itself shows the forward hole almost centered under the cone.  Which is it? 



Because I can't visualize the geometry of the rudder cable path yet, I'm concerned to move the hole in the nylon fairlead down to match the specified cutout location, out of concern for interference.  Neither do I want to move it up so it exits in the center of the cone without some word from a builder who has installed the actual cables.  



Sorry for rambling, but I'm needing some words of direction or reassurance from those who have gone before.  By the way, these are not Zenith factory parts since I'm scratch building.



Thanks in advance for any help you can give.

Larry,



My regular-build kit skins came with the 8X20 oval already cut so the hole position was fixed.  I just centered the fairlead hole and cone shaped fairing all up with each other and moved on.  When I got to the point of installing the rudder and attached the control cables, they all lined up just fine.



I would not worry about overthinking this one too much.  There are plenty other issues that you will fret about as you work your way forward on the fuselage. 



Good luck,

You're going to have to trim the bottom of the fairing so that the  

center of the cone lines up with the hole in the fuselage. I just  

centered the fairing over the hole in the fuselage and trimmed the  

bottom even with the bottom of the side skin. The fuselage cutout is  

the reference, the fairlead and fairing should be lined with up that  

cutout. Many of the parts have extra metal on them that will need to  

be trimmed to fit.

The responses make sense, but I have two quick follow ups.

  

 1.  On skin from the factory, is the bottom of the rudder cable cutout aligned with the top of the bottom longeron?  If not, how much is it above that line?

  

 2.  During installation, is the slot in the nylon fairlead parallel to the top of the longeron, or does it tip up?  I don't yet know the geometry of the rudder cable.

1. As I recall, the bottom of the cutout is aligned with the top of  

the longeron.



2. The cable does angle downward a bit as it passes through the  

fairlead but not by much. You could leave it parallel or angle it  

slightly, it won't matter much.

Thanks everyone. Wouldn't want to build one of these flying machines without the list!
