Re: Kitfox-List: Routing Of Wiring For S7 SS Trim ActuatorDave,
I think that is what I would do. I helped a guy finish a Series V with
a 7 Firewall Forward kit. It had the center console. It was an old kit
and the previous owner had run some cheap automotive wire to the trim
actuator. I had to replace that and it was a chore. Yes, I ran it
under the baggage area and it might be a good idea to run the wire to
the bulkhead, then leave enough length and do the final routing after
fuel lines and cables. As I recall, with the rudder cables and flap
control tube moving around it was a bit tricky running the fuel line and
the wire so there would be no chance of chafing. Not that there is
inadequate room, but finding hard points to secure the lines so there
wouldn't be a chance of movement. I think that is one disadvantage of
the console - what is down there remains hidden until each annual - more
on that later. Actually the console was a bit of a challenge as the shut
off valve and the rocker switch were mounted to it and had to be
connected after installation through the access holes.
As another thought. I have a hearing disability and to enhance the ATC
communication, I mounted a mini stereo jack and USB port to the seat
back which will support a Blue Tooth unit to my hearing aids. Like the
console, I thought it would be good to be able to remove the seat for
annual inspection with minimal effort. With that in mind, I cut an oval
hole in the center of the seat back and mounted the two electrical
outlets to a metal fitting that clamps to the cross tube that supports
the seat back. The fittings are accessible through the cutout. This
way, removing the seat is just a matter of cutting the Zip Ties. I
didn't think of this with the Series V, but I wonder if a bracket could
be made up that would support the fuel valve and rocker switch that
would be mounted permanently to the floor boards and cut a hole in the
console top so the console would not be the support, but just a cover
and could be removed simply by removing its securing screws. As I think
about it, it was this part that caused the chafing worries as I planned
the whole thing, but wasn't really certain what it really looked like
under there as it took a flashlight and mirror to see. Thinking about
it reminds me why it took about six months to finish this project which
essentially only had the wiring and plumbing to do. Most was redone,
though and the plumbing was a nightmare, but that is another story. I
like inventing things and one thing - totally off the subject - I made
up for him was a cowl flap assembly that would allow him to open and
close the NACA duct for radiator air and temp control. Haven't heard
how if works.

Thanks for your suggestions Lowell. I was hoping to avoid using
conduit, as it adds weight, and this is a 2-wire sheathed cable anyway,
which provides added stiffness and wire protection. So the bottom
stringer idea is a possibility. Am I correct in assuming that you
routed your wiring under your baggage compartment? Based on your note
regarding the crowded conditions at the seat front, it sounds like it
would be best if I only route the wire as far as the rear of the cockpit
for now, and then finish the routing to the console when the other
systems are in place.
Regards,
Dave

Routing Of Wiring For S7 SS Trim ActuatorDave, Mine is a Model IV, but I
have trim on the rudder and elevator plus the aft position lights there.
Just for a couple of ideas, My first Model IV I drilled some cross
holes through the bottom stringer that I then
tied the wire bundle to. I did the same on a current IV project. That
would put the wires where you want them for a console run. I put
connectors on the wires so in the event of servo or lighting issues, I
could simply unplug the units and put them on the bench. I know of
some who have run different types of tubing to the back so wires could
be run through it, something like the conduit electricians use. Some
have used rigid PVC and others have used the black poly landscaping
irrigation tubing. Another guy ran rigid aluminum tubing (maybe 3/8")
where he wanted the wires go go and tied the wire to the outside of
that. A thought on the console run - it gets quite tight right at the
bulkhead at the seat front. you will have flaps, rudder cables, fuel
lines and wires going through there. To allow for free control movement
and prevent chafing, it will require a bit of planning. Some sort of
conduit there might be a good idea.
Hope this helps a bit.

Subject: Kitfox-List: Routing Of Wiring For S7 SS Trim Actuator
I am building a Series 7 Super Sport, and I am at the point of
installing the electro-mechanical trim actuator. Can anyone who has
completed their aircraft provide me with any detailed advice on the best
way to route the wiring from the tail through the fuselage to the switch
on the console?
Thanks,
Dave
