 :) :)Hello Again,
Whilst I have been using the usual bent wire in my steering connections, I don't like it as it just does look right.

In the October Model Boat Mag, page 12 it shows a fitting from servo to rudder arm which looks much better.

Can anybody inform me where i can purchase such a fittingMany thanks CERES.

I would start at a Hobby shop that handles RC Aircraft. There are all kinds of fittings that you could use, Dubro ( http://www.dubro.com/ ) in the US makes all of the connections that you will need. Click on the black Dubro emblem on their web page. Remember that you only want one end with an adjustable link the other end should be fixed. If the rudder end is the easiest end to get at then the end on the servo should be fixed or vise versus if the servo is the end that you can get to. A "Z" bend in the fixed end is usually the way that I do it on both my boats and air planes.  I hope this has been of some help.

thanks Also Andre -- I am needing lost of new rod configurations on my steam launch with three channels coming my direction!!

Hi there Andre

Can you explain why you should only have one adjustable link on a servo to rudder linkage?

Colin

I think the idea is that you only need one, having both ends adjustable is usually unnecessary

Thanks Andy, but I am using GOLD-N-ROD which is a Nylon rod in a Nylon tube, and this seems to be designed for adjustable fittings at both ends - the fitting screws into the rod. I guess that perhaps it is a question of cost - why use two, when you only need one.
However, this system works well for me with two adjustables. I did wonder if there was a fundamental no no for this !!

[andygh]

No reason I can think of, apart from the extra cost as you say

There is nothing to prevent you from using a piece of 2mm or 2-56 threaded rod in one end with a Z-bend to connect to the servo arm (or rudder arm), and save the other adjustable link for another model, as the rods are usually pretty long.

I use a clevis which is screwed on to the end of the push rod, these will turn pretty easy, if I have one on each end all it seams to do is screw one in and the other one out. If one end is a "Z" bend then I can screw the one either way and accomplish the fine tuning that I need to dial in the push rod. An other problem that has happened to some people flying aircraft is that the vibration will cause the push rod to screw in or out in both clevises and some times the push rood will completely come unscrewed on one end or the other and then all you have is a smoking hole in the ground that used to be your airplane. I realize that unless you are running a high speed gas boat vibration will not be a problem, but old habits die hard. See the drawing that I have attached and see if that does not answer some of the questions, if not let me know. Oh by the way the reason that I use this system is that it allows me to put the servo anywhere that I need so I can get to it easily. This style of push rood is very flexible, depending on the size it can be bent into a 4" circle and still be very easy to move with hardly any resistance.

PS It looks like you will have to down load the diagram to see the text clearly. sorry about that.

Yes in RC aircraft they have been known to come unscrewed on one end and screwed in on the other end, result no airplane.

The end fittings you guys are talking about are known as Quick Links or clevises they MUST always have a locking nut fitted to stop them self adjusting not like the ones in the picture 

You can bend one with end with Z benders purchased from Al's Hobbies or Hobby Stores around the country they make a perfect and easy bend.

[amdaylight]

Yep thems the critters

It is frustrating not to know what is being talked about. What is GOLD N ROD?
Also how do you fit the ruddert end?
Cheers.
