Hi David,
Whilst I do not disagree with the advantages of plastic tubing being used in this manner, as an inspector who each year is required by LAA to certify the condition of these cables, I have to add that it is impossible to inspect cables that are inside a plastic tube. Those who have gone down this route for protection will be aware of the work involved in gaining visual access to the entire length of cable that lies out of sight.

One tip for those installing rudder cables in a mono is to
run them inside the light plastic tubing (used extensively
in gliders) through the wheel well. It is virtually
friction free and protects them entirely from damp & grit.

use this info to find the spec of cable you have
the nicopress is usable on either. best to ck spec on
swaging
the best place I know of for flight control cables is
Mcfarlane aviation (USA)
also a good source for other "stuff"

Yes, stainless was developed for yachts, sea water
contamination resistant. There isn't much bending in the
Europa so no worries about fatigue.
Must be the multi strand stuff though, 7X19 springs to
mind but anyway it's fine wire strands for flexibility.

Also be sure you use the right crimps, plated I think,
not plain copper. Get a second opinion, I not as young as
I once was!

Hi Graham,
Wish I knew if it was what was supplied by Europa. I’ve
had the kit too long to know, things have been moved
around, and I don’t recall the Europa stuff ever being
labelled.
Maybe someone else might be able to clarify. Worst part
is, it looks old even though it mightn’t be. It reminds
me of a Hills Hoist outside clothes line cable, but I
think that is more of an Aussie thing. I actually don’t
have enough Nicopress sleeves now so I’ll need more of
those anyway, so I can get some more pretty stuff 
You normally use Stainless Steel cable by choice don’t
you??
