Steve,
NICE! That?s what I?m talking about. Very secure rudder, and elevators for -A models, and taildraggers too. How thin is the web on the elevator counterweight control lock?

the web = .1 inch. this will not work for some that have tight clearance.

Rather than having to tie it every time, how about using an elastic of some sort to give the ropes some stretch, and hooks or carabiners to clip onto the holes in the locks? You wouldn't want a long piece of bungee as that could let the rudder find some resonance point in certain wind conditions, but perhaps a 2-4" piece of elastic tied into the rope somewhere along the length would be enough to take up the slack?

that could work. BillL mentioned that the bungee should have a rope stop if you went that way. For me, I will use a rope if I can learn how to tie a proper knot. What type of knot should I use? My rudder will need to depend on it. Also, what would be a good rope?

If you use a rope you will need some way of keeping the lose ends off your horizontal.
You don't want rope ends flapping around in the wind scratching your paint work.

yes, I don't want flapping ropes. do mountain climbers use something for that?

Dunno, but a velcro cable cord organiser would probably work -

A rope ratchet might be good here------you could put a bungee segment in also to add a bit of "give" to the system.

If you go that way, might be good to make up a different way to attach it, the hook is kinda big and clunky for this application.

Maybe just tying a couple of loops into the rope length, and then putting a bungee between the loops? That way if the bungee fails the rope at least has a finite extension length.
