Hi  

   

I have been wandering through the archives for info on rudder wiring. I believe that the preferred exit for trim servo wiring as well as other wiring is at the base of the rudder. For me wiring is a dark art at the moment and I am a bit concerned about building myself into a corner. In particular, my access to the rudder interior will be somewhat limited if I roll and rivet the rudder leading edges.  

   

My question is: how are wires secured in the interior of the rudder so that they do not chaff against the rudder stiffeners? Should I wait until wiring is done to complete the rudder?  

   

Inquiring minds need to know

Hi Les,

 1-The servo wiring  will terminate at the servo in the forward section of the  tailcone.

  

 2-The trim motor wiring will  terminate at the trim motor just below the forward emp fairing.

  

 3-As for the rudder....depending on  your lighting....you'll end up with wires for the strobe and nav light passing  through the lower section of the vertical stab spar. Easiest way (imo) is to  drill just below the bottom rudder hinge bracket. You may need to place a  grommet in from each end of the spar for protection. Also, you may want to  drill just off to the side as to not penetrate the tail tie down reinforcement.  This will line your wires up just below the lower rod end bearing, allowing you  to pass the wires through the lower fairing. For clarity....the wires will pass  through the leading edge of the rudder in the opening just above the fiberglass  fairing. I've done 5 or 6 these now and I always use a good connector  in this area. Leave your harness long enough so that you can pull the tail light  out and disconnect the wires for a) tail light replacement and b) rudder  removal. The harness and connector will be stowed inside the lower  fairing...savvy??

  

 Also, the wire for the lights can  terminate at the bolt (use a ring terminal) at the lower rod end bearing  attach.....rudder side of the spar.

  

 Hope this helps....Good Luck  Les,

Hey Les....the bottom part of my  post should read 'ground wire' can terminate at the bolt at the lower rod end  bearing attach. Sorry for any confusion :^).

Hi Rick



I understand what you have posted - many thanks. Is there a chaffing issue for the wires that run the length of the rudder interior? I would be concerned about chaffing against the rudder stringers or is this a misplaced concern?

Hi Les....yup...I'm missed it  (sorry).....posting my reply here for archives:

  

 -yes...build your rudder  'completely'...this includes top and bottom fairings. You can send it off for  paint as well.

  

 -yes again...the wires will run  through the lower vert stab spar...just below the lower rod end bearing attach  bracket (off to the side of the internal tie down mount). Route the wires into  the rudder about 1/8" above the upper cutout of the lower rudder fairing....you  can notch the fairing in this area if needed to accept the wires.

  

 -as mentioned earlier....make your  harness long enough to a) pull the harness out of the light attach fairing  portion of the fairing for light replacement and b) to pull the wires  'forward' for rudder removal (you never know) using some type of plug connection  (molex or spade will work...just makes sure it's small enough to pass through  the hole for the light).

  

 -lastly...the wire loom will be  laying in the bottom of the fairing for time and all eternity......your concerns  of wire abrasion and chaffing are valid...the inside of the fiberglass fairing  is rough. I always wrap my wire loom in this area with some 'spiral wrap'. You  can buy it at ACS or at your local Radio Shack. The stuff at Radio Shack is a  lot cheaper and will work fine in this area but the stuff from ACS is more heat  tolerant.

  

 Good luck and Happy  Holidays.

 Hi Rick



I posted this after your last post on the RV10 list and  perhaps you missed

it. I have taken the liberty of sending it to you directly  as I am still a

bit confused / uncertain as to whether or not I can form the  rudder leading

edges in advance of installing the rudder wiring. 



I am  assuming that the rudder lighting wires run through the interior of  the

rudder - is this the case? 



I have an opportunity to have some of  my completed sections painted and

would like to include the rudder section  included when I drop them off at

the paint shop.



Regards & Merry  Christmas



Les Kearney
