Pull-Pull Cable Material

Just wondering what people find makes a good pull-pull cable, ie strong and no stretching. I'm going to use one on my DeHavilland Twin Otter. Rudder area is about 34 sq in., so I need something stronger than the really light stuff used by the micro flyer type airplanes. Thanks for any input!

or 20lb or even 30lb spectra fiber. I've used the PowerPro brand as that is what I spool all my fishing reels with. Berkley Fireline also works.

Any of the superbraid fishing lines will work. Power-Pro, Fireline, but my choice is 10lb test Spiderwire Braid. Even though it says 10 lb test, you can hang a 15lb/17lb weight on it before it breaks.

It is very thin. The same diameter as 2lb monofilament. Has absolutely no stretch, and comes in a moss green color that seems to dissapear.

It's down side is that it's not very abraision resistant, is so thin that it can give you a paper cut, and so smooth that the knots can slip if you don't glue them.
About $13 per100 yards, at your friendly fishing store

I have used the plastic coated leader material they sell at Gander Mountain. It is 20lb test steel cable, can be purchased in other strengths, that is covered in black plasic. It is very light and it has no stretch. Most of the fishing lines do stretch.

Careful with Kevlar it is not UV resistant.
I have used Berkley and other brands of 10lb stainless stainless from stores that sell saltwater fishing tackle.
I've also used 10 lb Firewire. Walmart sells it.
I've got some 25lb firewire but have not used it yet.
You can use crimp sleeves (or small brass or aluminum tube)
I pass the line through the sleeve, thru the horn, thru the sleeve, around and thru the sleeve again. I keep passing it thru the sleeve until I cannot get it thru anymore. Then crimp it and put on a drop of thin CA to lock it in.

Ugly sticks,
You said Spider wire "... so smooth that the knots can slip if you don't glue them. " Don't you hate it when that happens when you have a 40lb bull dolphin on the other end?

Dal, Yeah, I think I'd hate that. But if I ever hooked one that big, I wouldn,t lose it because of a knot.
I use a mono leader with a 10x10, or albright knot to the braid. They don't slip. That wouldn't work in a airplane pull-pull system though. :-)

You mean you caught Flipper ? Well I guess it's good that he got away then. Would hate to end that high paying film carrer early.

dolphin as in Mahi-Mahi or dorado not dolphin as in bottle-nose porpoise. You need to spend some time on the water!
