Looking for post re using PEX as conduit from under-seat area to tail

[FoxTrotter]

A few weeks ago, I saw a post with photo(s) re using PEX as conduit for the wires running to the tail. Can anyone point me to that post?
Thanks -- Michael

Pex plumbing pipe is way too heavy. Use corrigated, slit, wire loom; or if you want something stiffer but very lightweight use the Home Depot, etc. drip irrigation plastic pipe and slit it yourself if desired.

I left the tubing in the wing spars because there are many sharp rivet ends poking thru the spars and no way to secure the wires from bouncing around in turbulence.

Don't know that I ever posted a picture of it on this site, but that is what I did for the wiring going back to the tail on my Kitfox 4. On my Avid Flyer, I mounted the battery as far back as I could, and tied the battery cables to the conduit so it would stay in place as well. Here is a picture of the red pex on the bottom of the fuselage of the Kitfox. Used blue pex on the Avid Flyer. JImChuk

Thanks, both! And thanks for the comments on weight and alternatives.

In the post I'm trying to find, the poster used white pex and ran tail strobe, elevator trim, and something else. Still looking for that post.

Thanks--Michael

I think this pic has the blue pex, and the red is the battery cable, no? How do you access the battery -- did you put a large inspection panel on one flank? How far forward did you run the pex?

I plan on using the milky white polyethylene tubing like you get at the hardware store. About 1/2 the weight of PEX

And why have you chosen that vs, say, the split corrugated wire-wrap?

Hard to fish a wire through a corrugated split loom if the need arises. The corrugation will impede pushing a wire through, and the possibility that it exits prematurely through the split is there too. Corrugated split loom is for wire protection, not for fishing wires. Technology changes and I want to be able to run new wire to the back of the plane if needed.

I preferred the irrigation tubing over the corrugated because "fishing" a wire thru is easy. It can also be easily slit with a pocket knife if desired, and the slit stays closed; it takes quite a bit of effort to open the slit and pull a wire out. In fact in a couple of places where I needed a wire to exit I cut a little wide spot in the slit so the clamping force of the slit would not damage the wire insulation over time. Handy stuff, cheap and lightweight and easily cut or bent.
