I am about to wire the tail light/strobe on the bottom of the rudder. 

What is the best direction to run the wires out of the rudder and into

the back of the fuselage.  I am inclined to run it out the bottom of the

rudder (maybe 1/2" up) and upward a bit (about 2-1/2") and then into the

back of the fuselage. This will allow for the twisting of the wires

during the usage of the rudder and minimize the stress on the wires in

between the vertical stabilizer and the rudder.  Or should I run a loop

going upward and then back down and into the rudder and fuselage.      

/\        staying away from the bottom rod end.  I can also cover the

wire with the 

                                __/   \__



spiral wrap to protect the cable from abrasion.  Any help would be

appreciated.

Hello Jim,



Attached are photos of how I accomplished this task -- not the

prettiest, but effective. The slot on the rudder butt allows the wires

to stay put without bending stresses when the rudder is exercised. There

is about 3 layers of heat shrink protection over the wires should

excessive rubbing occur, which I will monitor. In a "static" condition,

there is little if any contact with the wires.

I was going to put a connector there, until I realized that it would just be

a flex point.  I ended up drilling an opening between the tie-down mount and

the bottom hinge and using a grommet.  The wire continues down into the

bottom fairing and there's a fair service loop so I can make the attachment

to the Whelen assembly outside the rear of the mount.  Once in place,

there's little movement of the wire at the front of the rudder.  I still

intend to install some rubber material, left over from the fairings below

the horizontal stabilizer, into the opening in the rudder leading edge. The

idea another person had of using heat-shrink tubing as anti-chafe protection

is excellent; you could also use some of the nylon woven tubing used in

bundling wires and hold it in place with a little heat-shrink.  I don't

think the nylon would wear through and it would look very custom.

 May not be the best, but this has worked well for almost 450 hours for me so far...

Hi Mark,

        Did you run the cable into the rudder by expanding the opening

for the bottom rod end?  Thus letting the cable just "drop" into the

lower area or did you use a grommet in the rudder to get it into the

lower area?

 Hi Jim-

  

 The wiring exits the fuse through a grommet in the VS spar.  I cut a slot side to side in the rudder bottom that the wires pass through just wide enough to clear them when the rudder moves to each stop.  There is maybe 1/2" of glass between the top of the slot to the opening for the lower rod end cutout.  The wires just drop down into the rudder bottom and go aft with enough extra length for a "service loop" to allow the strobe/taillight to be removed to expose the wires for disconnection via an AMP connector on a short pigtail from it.

  

 Feel free to contact me off-list if ya'd like a better description...

  

 Mark
