Default N200LZ: Chapter 7 - Rudder Conduit

I am running my electrical, rudder conduit, brake lies, etc. through the floor and walls of the fuse prior to skinning.
I'm planning on using the matco brakes.

What I am hoping to determine prior to running the rudder conduit is where do I need to end up in order to connect to the rudder pedals.

If I could get a measurement in the format of F# & WL# as to where the connect point is on the rudder pedal assembly, I would appreciate it.

TMann, Are you burying conduit in the floor of the fuselage? Trying to figure out why your running these lines now?

I'm running them in the walls. After you finish chapter 6 and before you skin the outside of the fuse, you can slot a track and run some Nylo-seal. The cable is threaded through later. This is an alternative to running it on the inside.

Anyway, it's easy to figure out where to exit the side in the hellhole but I don't have a reference point for up front.

Here's my take - Up front, bring them out right at the end. From here you can embed them in the nose foam when you build it, to come out just aft of the bulkhead at the forward end of the NG30's. Leave about 3 feet of hose to allow for the nose and a curve back to the master cyl.

John, I'm talking about the cables and where they attach. Is this what you are talking about here ? ....... or are you referring to the hydraulic lines?

Sorry - I was talking about the brake lines. Bring out cables just forwad of the IP, except for those going to the nose for lights etc. You could also bury the pitot tube in the nose before glassing the inside. I always thought it looked tacky when looking in the pilot side of a cozy on the line and seeing all those wires and stuff running down the wall on the passenger side. Of course you still have the rudder cables. I installed a cover over all that with a slit for the rudder cable.

Dang, this sounds like an interesting idea. I have never seen inside a finished cozy so it had never dawned on me. I just assumed all the wiring and lines ran under the arm rest or the heat duct.

What kind and size of conduit is used?

chapter 7

For anything that might require a "Change Out" or will be put in later, I'm using the clear plastic tubing you find at Home Depot or Lowes. I'm using Nylo-Seal for the conduits that will contain the rudder cable.
I have heard of some builders using a thin wall copper pipe to run electrical and thus carry the ground in the pipe vs. a separate ground wire.

It's nice to have everything protected in the fuse skin, just plan ahead (i.e. draw out your strake cutouts, landing brake etc.) as there are some areas where you really don't want this stuff.

John - I finally found the reference as to the rudder pedal in chapter 13 (I had been looking in 16. DOH! ) I’m planning on having the conduit (Nylo-Seal) exit the skin at a shallow angle at the same level as the attach point on the rudder pedal at about FS 28 and leave plenty of extra to work out any last minute alterations.

The one thing that can hold me up at this point is the antenna. I'm hoping they arrive today so I can have a productive weekend.

Thanks for the input!

.....and the magig number is (drum roll please) 6.75 inches off the floor.
Thanks Chrissi!

CozyGirrrls will be making my rudder pedals to handle my matco brakes.
(and soon my 20B engine mount )

I'm shooting for a more rounder fuselage so I hotwired a curved exterior panel that will be micro'd to the original foam before shaping and sanding.

I also hotwired 3 channels on each side. The lower two are 2 inch diameter tubes. The upper channel is 1.25 inches and will terminate at the strake. The rudder cables are contained within the original foam wall.

These channels will carry all of my electrical, hydraulics and vacuum if needed.

Okay now I am jealous! I was thinking of doing exactly what you’ve done but on the bottom of my cozy fuselage, I didn’t dare due to increased weight.
Dang that is going to look awesome!

Truely Awesome!
If the same technique were done and put the armrest inside edges straight up where the old fuselage sides were and extend the strakes to the instrument panel you could be mighty roomy in there.
Three cheers for colouring outside the lines.

Thanks for the feedback!

I'm finally getting my plotter out of the box and setting it up for the next step.
I need to plot out templates for the strake at BL23 and where it meets up with the fuse. I'm using the foam mold that I'm putting together for the strake skins. I have the piece that will line up with BL10 (which I cut away for the original profile where I mated the strake mold to the fuse) and will project my template out to that point.

Once I cut the strake profile, I'll remove the BL10 filler piece to get back to my matching profile. Then I'll slice off a 4 inch thick piece (to match my original foam thickness prior to hotwiring the curved fuse piece.) This will give me the profile I need to cut out of my extra fuselage foam to mate up with the molded strake and take into account the various curves of the design.

Take my side pieces off, mate them to my original foam material, hotwire to the new templates and reassemble.

I'm documenting the process and will put it on my website (if I can ever get out of the garage!)

I know someone out there is going to ask about weight so here's what I have so far.
Currently I added 9.48 lbs.
I won't have a final figure until I cut out the piece for the strakes. I'll weigh that and subtract it out and will post the final figure at that time.

You won't have any problem with weight that the 20B can't overcome
