I need a large double sided control horn that can attach to a rod with a set screw. The rod controls the rudder on a 1/4 scale plane and I need to arm to set up a pull-pull system. Where can I find these?

Thanks,

I know Dubro sells a large servo control horn. Is this what your after?
A long and strong enough horn to connect a rod to!

I guess it can best be described like the double control arm on a servo but for use attached to a rod. I need a larger one to get more leverage for large applications on 1/4 scale planes.

Could you use a brass bar.
Glue up a base for the brass, mount the the brass with a bushing to the base. Run control rods from the Servo to the brass bar. Then from both outer edges of the brass bar connect your pull pull links and run them out to your control horns. Use two 1/4 scale T horns on the control surface, match them back to back instead of using the back plate.
Am I on the right track

Try gator rc or nelson hobbies both have unusual control horns etc

The rod that controls the rudder is internal (for scale look) thus the need for attaching to it. Seems like I've seen these before but just can't remember where. The device would be like a bellcrank but 180 instead of 90 degrees.

Well I'm way out on this one. Sorry :stupid:

Is this what you are talking about, this one is from nelson hobbies

Yes but attached to the other end of the plane... the rudder. It would need a set screw to be able to attach to the rod which accuates the rudder.

Do a search for rudder control horns, here's a couple

Thanks for the link but this is not something that attaches to the control surface. The rod that accuates the rudder is internal and looks more like a bellcrank but 180 instead of 90 degrees and uses a set screw to afix itself to the rod.
