Hi listers,



I'm still not sure what happened, but I got bumped off the list for a few days.  I'm now back "ON".



I am interested in hearing from all XL builders (dual stick option) about how you have, or plan to route the pitot & static lines from the wing to the panel. I think I have thought this through, but I have discovered that others may (and probably will) have better ideas than mine.



Thanks in advance

The only opening through the spar center section is the flanged hole in the midline. Once you install the rudder fairleads there is only a little space left to run wiring through there.



I'm planning on using the space in the center console above the spar center section to route wiring and tubing up to the area forward of the instrument panel. The biggest consideration in that route is the clearance for the movement of the elevator horn and the threaded rod connecting it to the dual stick assembly. 



There should be adequate room to bundle the wiring and tubings that have to pass there into two bundles, one on either side inside the console. The entire top of my center console is removable with #6-32 screws and nutplates so I will wait to run the wiring after the cables are rigged to make certain that there is no interferrence.

i amrouting them through the left side of the seat base, up to the canopy sill, then under the panel.

option two was to drill two holes right of the wing root.don't like that one.

Ed, I'm not trying to rain on you wiring and tubing parade, but when I tried to route them along the top corners of the console the control bolts bumped into them on both sides. I suppose you might try to route them along the inside sides of the console below the arch of the controls ? I on the other hand just cut a couple small holes in the center section inside the area for wing bolts, put in rubber bushing to protect the wires and tubes and ran them there. Not a perfect solution but it works. Hope your doing well and making good progress, Best regards, Bill of Georgia

Jay, everything is pretty tight in these places. I ran the tubes into the cockpit by making two holes down near the left side seatbelt attachment point. There I attached two 90 degree fittings. I ran the tubes under the seat pan through a hole into the area under the thigh area where there is good access. I made two holes in the center section and connected the tubes to two more 90 degree plastic fittings outside the center section and ran them along the front of the center section to the side of the fuselage and up in front of an upright "L" angle brace and up in behind the panel for attachment. It was a bear, but out of sight and functional. I added a small protection plate over the fittings so my big butt doesn't bump them getting in and out of the plane. When I installed upholstery panels all was covered and protected even more. Best of luck, Bill of Georgia

I routed most of my cables and tubing through the center spar opening  

on either side of the control stick torque tube at the same level as  

the torque tube. There is a gap between the outside of the two  

extruded Ls and the flanged hole through the spar. I put vinyl  

moldings on the edges of the hole and routed my bundles through these  

openings. I tied them back against the sides of the tunnel and  

covered them in spiral wrap. That way, no matter how the stick moves,  

no part of it can contact the wire bundles. There is room in the arm  

rest tunnel for your wiring as long as you tie it down so it stays  

out of the way

Jay,

  

 I have dual sticks and dual brakes in my XL. I  agonized over the routing of my pitot and static lines and also my brake  lines.  I understood from Zenith that they routed their lines through the center spar center lightening hole where the  rudder  control cables pass (I asked them about the advisability  of putting a hole through the neutral axis of the center spar webs and they  advised against it).

 I found that I could route the lines through the  center spar.  I covered the lines with ribbed plastic tubing (automotive  wire bundle type, procured from the airplane parts dept of Wal-Mart) for chafe  protection and tied the protected lines down on both sides of the center spar  with adel type clamps attached to the lower skin, to prevent  movement.  There is no interference with the controls or control  cables.  This method also permits filling the brake reservoirs from the  brake bleed fittings, as all the lines are below the brake  cylinders.

 I routed my electrical lines under the cockpit  rails.
