What can I use to crimp Pull-Pull rudder wires? ( I mean the actual retainers themselves.) Does Brass tubing work?

Try reading this, it might help.

G'day Mate,
Try your local fishing tackle shop, the ones they use for leaders work well. & they are cheap as chips.

Plain ol' brass tubing will work well

This is from a Dave Patrick instruction manual. It does a good job of showing how to thread the crimp.

Hope this helps

Is a tiny drop of CA on the crimp a good idea? or would it cause the line to be brittle?

What are you using for sleeve that you crimp. If using as suggested by someone 60# by the time you put three strands inside the crimp it is going to have to be quite large. I have been buying 40# from Gander Mtn. and they also sell the crimps,but not large enought for 60#

On the GWS sized planes I use 6# monofilament line. Each hole has a 1/2 knot with some tension. When the stretch is right, I touch the wet tip of the CA tube to the line ONLY And LIGHTLY.

Just enough to lock the 1/2 knot where the lines are crossing each other. It is simple to pull on the line to release it for crash repairs. NEVER fill the servo arm hole with CA. That forces you into cutting the reuseable line.

Big planes get the Braided Dacron fish line. NO STRETCH. Same CA treatment. Big difference is the CA is wickedto about a 1/2" away from the knot. So to keethe line flexiable at the holes. CA the line close to the screw hole. I take a tooth with a little Vasaline and coat the screw hole parts so no CA gets a grip in there.

Light, Very accurate, invisible, no slop or binding and easy to adjust. Heat or cold changes nothing. CHEAP!! String and KNOTS.......Allows ALL servos in the nose if desired to help tough COG jobs.
