No for the following reasons:
1. I already had some a/c quality #4 cable, as used with C130 a/c
generators.
2. The oval plastic ducting available for domestic house electrics in
the UK provides a perfect fit to enable end feeding the cable from the
battery to the engine bay.
3. As the total weight penalty was about 1.5lb then the difference
between types of cable wasn't going to be significant.
Thanks for the info. I will bear it in mind for any future projects.

Hi Nigel
Did you consider using CCA wire ? See:

William,
CCA is "Copper Clad Aluminum" The aluminum strands of wire are clad with
copper using a cold fusion process, similar to friction welding. This stuff
has all of the wieght advantages of aluminum, but none of the disadvantages
when it comes to terminating it.
I am told you can even solder this stuff with regular lead/tim solder. I
have a short piece so I must try this to see if its true. It weights almost
half as much as the copper equivalent.
The down side is that #4 costs about US $3.25 per foot.

Nigel,
I used #4 welding cable which was nice and flexible and not very expensive,
but I remember when I was bringing the 25' roll home thinking "darn this
stuff weighs a lot"
I suspect that the thick flame proof rubber insulation added a weight
penalty over the cable you used. I really wished I weighed it at the
time..... maybe I'll buy a short section and do a rough calculation.
I tried to pay attention to weight in my aircraft, it came out at 860lb,
about average for a 914 mono, but I often think until you have built an
aircraft you really don't have a great appreciation of its importance. Some
people have built 914 monowheels that have come in at 790 lbs..... I sure
wish mine weighed that.
I look forward to seeing your calculations of the "battery in the back"
weight trade off.

William,
Copper Coated Aluminum. Conductivity of copper with the weight of
aluminum. Great stuff, but it requires some special care on
connections.
If I can find my link, I'll add it to the posting later.
Good building and great flying,

Thanks
I'm like you...I worry about 3.25 per foot in an aeroplane which will cost
eventually in the region of USD60k.
Is this ac grade stuff - do you get it from AC Spruce?

It is too easy to get carried away adding weight to the aircraft. This
was especially a problem when the MTOW was only 1300lb. Just how
important it is depends a lot on pilot and passenger weights. If you can
carry at least 50lb baggage and full fuel with 2 people on board and
stay within MTOW the use of the Europa as a cruising has not been
compromised.
When it comes to allowing for weight of fuel be aware that many of the
fuel tanks expand with age. My tank started off with a 69 litre
capacity. It now holds 76 litres. This is good for range (about another
25 minutes flying) but it does add about another 5lb to the fuel weight.
Regards
Nigel Charles

The equivalent #4 CCA is thicker than #4 copper, also a lot stiffer.
Attachment to battery better be well thought out to deal with stiffness.
I had Eric use his hammer crimp to crimp on a connector on a sample, it
hand pulled off, so a better crimp and solder is in order.
I calculated weight savings, and will take the mini hit on weight for
better flexibility, and more important the smaller diameter. I calculated
for aft battery.

Subject: | wing conduit mod |
--> Europa-List message posted by: Rowland Carson <rowil@clara.net>
I just checked the PFA website for the list of "standard" mods, and
don't see anything there about wing conduits.
I think I'd like to install conduit before I close the wing, not just
for the possibility of wingtip lights or strobes, but also because
the conduit can provide a very handy hole to insert a support when
turning the wing over.
Does anyone know if there is a "standard" mod in the pipeline? Or
indeed has anyone in UK got wing conduits as an approved mod? Or is
it a "non-mod"?
regards
Rowland
(actually thinking about aeroplane-building again!)

Rowland,
w/o regard to PFA issues, I used some feather-light plastic irrigation
pipe from a garden shop. My hunch is that it would not be robust enough
to serve as a wing rotator support and that function, if desired would
be best dealt w/ separately. I'm unaware of any "standard" mod.

Cheers,
If you want to compare weights, I ordered 20 feet of #4 CCA
(copper-covered alu) wire from Perihelion and Eric Jones. I expect to
install a 17Ah battery under one of five compartments built under the
extended bulkhead 'shelf'
It weighs 48.75 gm/ft. I was going to use #4 welding cable (rubber-covered)
which is 127gm/ft - because of its flexibility and rather innocuous smoke
when heated (archives). I don't know the weight /foot of #4aircraft cable
but it may be determined I'm sure.
The length involved may be less than 20 feet, but that too I
leave to you. The advantages beyond the weight are (1) more flexible than
a/c cable; (2) better insulation than welding cable (a/c standard); (3)
yellow colour makes it more readily obvious; (4) fits neatly in 12mm/half
inch copper tubing for nearby ground - watch the chafing..; (5) Eric is
great to deal with and has excellent installation advice.
Minor disadvantages :
(1) More expensive - stop smoking, nothing much on a big ship;
(2) slightly larger - see 4 above.
I feel better about shifting the battery with this material, but of course
you are the final judge. Nevertheless, maximum time of starter engagement
must be calculated when using aft battery........
Regards

Rowland, I believe Ian Rickard has details of a conduit fitting which we
have used in our aircraft to our inspectors satisfaction.
