1-How does wiring from the rear of the fuselage get to the panel?(Under the torque tube-?) 2-What do you use to attach the brake lines to the gear leg? 3-Do the brake lines run under the bottom longerons and then enter the fuselage near the pedals or go up the gear leg and into the fuselage then where? I have a long way to go.

There are many approaches to the routing of the wiring and brake lines.
For the wires I have seen conduit in the center console and also wiring under both top longerons. With wires under the longerons one question is how to get the wires past 6B16-3 (left and right), the sloping braces at the outside of the seatbacks. Some route the wires around these parts in flexible conduit while others drill holes in the parts.
One solution for the brake lines is to enclose the channel on the bottom of the plane. Ed Moody posted a series of photos of this solution last September.

You asked some good questions that have been asked before. Search the archives where there has been a lot of discussion on each of the topics. I will give you my opinion and what I did. I am not flying yet so it is all still theory and subject to change given real world results.
1. You can get wiring from the rear to the panel via three routes. Left armrail, right armrail and through the middle spar opening and center console. I used all three. I kept power items in the center and left the armrails for antennas. I attached a picture of the stuff going through the center spar.
2. I used adel clamps screwed to the rear of the gear leg. The ZAC demo plane used stick-on tabs and some of these have lifted off. I asked ZAC about routing out a channel down the rear of the gear leg to imbed the bake line and they advised against this. See picture attached for what I did.
3. Brake line routing. ZAC says to route through the middle spar opening and out the side skins at the gear leg. I did not think I would have enough room there so I ran them below the cockpit floor and back along the fuselage bottom. Now that I have done this, I don't like the looks of it and may change back. Again, see picture attached.
Good luck on your project,

I bundled some of the wires from the rear of the plane (and the brake
lines) along the sides of the tunnel at about the same level as the
torque tube. That location keeps the bundles form contacting the stick
as it moves the torque tube. I also routed some of the wires and antenna
cables in a piece of plastic tubing installed in the channel under the
canopy side rails.
I drilled and tapped some holes along the rear of the gear legs and
attached the lines to the gear lets with plastic cable clamp and screws.
My brake lines enter the fuselage above the lower longerons near the
rear of the gear legs.

Most of the wiring answers are pretty consistent, run the wires under the longerons and through the center console. My brakes were also run through the cener consloe and then parallel to the spar exiting the side skin just behind the gear. I used a 1/4 inch round nose router bit and cut a slot in the rear side of the gear. The brake line sits in this grove and is clamped in place with small straps screwed into the gear sides

One "pretty" way to run the brake lines down the rear of the gear is shown
in the attached pictures. I don't know what the proper name for the special
"threaded post" nut and bolt shown is. Mine came from Lowes.

You can also google “binder posts”. Apparently one of their intended purposes is to hold together stacks of three-hole punched paper without a three ring binder.

Hi Bob,
Here is my solution for the brake line routing on the landing gear. It is a small fairing I made that includes little brackets which hold the brake line in place. I routed the lines along the cabin bottom from the front to the area you see in the picture and held it in place with a couple of standard clamps.

Well the pictures I posted were of a plane being built at Michael Heintz’s Quality Sport Planes. I know of two others built there with the same approach. My belief is that the gear is the most robust (over designed?) part of an XL.

O.K. just asking, just found it a little curious. I guess my thought is if the gear is strong enough to do the job with holes punched in it , it could be lighter and do the same job with no holes, but then again, I play left field without a glove on a pretty regular basis. LO&SLO John

Quick survey: has anyone ever bent the main gear on an XL?
Some are flying the Grove gear which is lighter. Has anyone bent it in a hard landing?
The European XL has a composite main gear but the whole plane is lighter.

I'm new... I've not yet purchased the kit, but I've built the 601XL rudder at the factory workshop...
Does Zenith provide guidance in the assembly instructions for these items (routing of wiring and brake lines), or is it up to us to figure it out? I can understand that each avionics/wiring install is different, but it seems like Zenith would provide guidance on the brake line installation?
I'm getting ready to order the tail kit (includes plans), so I'm sure a lot of questions I have will be answered when I review the plans.
Thanks, and I enjoy learning from all the experts here!
Regards,
Mike

There are instruction on routing the brake lines. It's just that none of us seem to like how Zenith did it. Little stick on plastic clips.
Nothing on running wires.

The brake lines can be streamlined and nicely hidden beneath a piece of
vinyl gutter guard that is cut down and attached
with Gorrilla Glue to the rear of the gear legs providing a nice channel to
run the lines.

Craig, I was wondering if it was acceptable to put drill holes into the landing gear like that? Did you clear this with Zenith before you did it? I'm not sure if this could cause some sort of structural weakness or not. I'm not an Engineer so I honestly don't know for sure.

As I mentioned those photos are from a plane being built in Michael Heintz’s hanger at Quality Sport Planes in Cloverdale, CA. Michael is one of Chris’s many sons. At least two other XLs have been built there using the same approach.
