Yes. Nylon, nylaflo, or poly flow tubing works great for this as they are
non-abrasive and tend to be self lubricating.

Carbon is way at the other end of the galvanic scale. You'll get corrosion
if you use carbon fair leads and they will emit black dust in your interior.

Stef,
I used a non-rigid plastic tube. Since it is only there as a chafe guard
rather than pulling against it like on a bowden cable sleev, it doesn't need to
be rigid. Just clamp in place at one end with an adel clamp and you are done.
See the blue tube along the left side of the cockpit in
Hi netters,
I am at the way to install the rudder cables at the position where the Seats
are in a carbon Fibre tube (so you will not hit it with your elbow). I heard
sombere that the steel cable will be Eaten by the carbon tube. Is that tru? So
if that is a problem i will order new tubes, but no

In my experience the cable will saw through most anything...however I have
no experience with carbon tubes. I would be concerned more with corrosion
since carbon fiber is so horribly corrosive.

You should search the achieve about this... if you are talking about
using CF for all of the plane, you will only gain high cost with no
usable gain, except in the seat pans.

No. Carbon fiber is laid up with the same resins and in the same manor as

It has been 15 yrs or better but at 1 of the gatherings Jeanett told a group of
use that she had an enginer do a load test of the wing and the carry thru spare
gave out before the attach fittings. She was woried about folks adding wing
extensions. It was around 92 or 93 Maybe even earler.

of holes in it.

If you still have the spring it might be worth the effort to reheat it

I don't know much about carbon fiber, but I have
routinely installed composite (fiberglass) rear mono
springs on early model Corvette's without problems.
I suppose something similar could be developed for an
airplane.

I built my tailwheel spring of about 12 inches using 28 layers
of 6 oz. cloth alternating unidirectional and bidirectional cloth,

I hope someone hasn't suggested this as I haven't been reading all posts.
If you want the tail spring to be composite, why not make it out of round

industrial suppliers. It could be set up somewhat like a Quickie

Yep, the stub airfoil and stub wing structure remain the same, but the outer
wing transitions from the RAF48 to the GAW during the first foot, and then
tapers down toward the tip using the GAW.
