3D SWB Wire Tensioner

[Notorious B.E.N.]

On my Edge 540, I have the Wire Tensioner's from SWB for the pull-pull cable.

I noticed that my cables (Don's Hobby Shop coated Kevlar) have some slack in them. It's not enough that I can move the rudder too far but has anyone ever noticed the cables developing slack?

I need to check some other things as well but I'm just curious.

Most All cables will stretch over time, I always check the tension on my rudder cables every time I go out to fly, just part of my preflight checks. Cable stretch is normal, just manually tighten to the tightness you want and go fly

Yup, I've noticed the same thing, they tend to stretch a bit with some use. After about 10 flights or so it seems like they've loosened up enough to cause some black so I just re-tension them and call it good after that.

That's how steal cables work, they must have a sort of flexibility well they suppose to do so if not, well, you've got the wrong ones.
Not only that even on very hot days or very cold days I see it.
I reckon it's something we all need to keep an eye on from time to time.
I've been using for a long time the gold plated from Secraft and before that Nelsson hobbies.

These are type i used for my 3DHS pull/ pull rudder , they have two set screws to secure the rudder wire and a turnbuckle to keep the tension. Manfacture is Secraft .

I've tightened my cables again on my 100cc Yak, no more threads available. Does that mean I replace the cables next?

Yes

It doesn't need to be tight like a guitar string but if it loos replace it.

Maybe OT, but I got rid of some jittering after I tightened mine. 7955s of course [emoji123]

You can use the old fashion way with the Velcro between the rudder counter balance and the fin.
If you ain't got it then use the method you've mentioned.
