Mike, here is an aviation maintenance manager, asking the same, maybe he can give you the answer in the near future.

nothing works as good as wiring & soldering the two pushrods together!

I remember people just making them before. One way is to take a piece of aluminum and drill three holes in it for the pushrods. You can then either drill and tap holes for set screws, or even tap the holes and screw the pushrods into it, or both even.

The simplest method is to use a couple of wheel collars and one long pushrod and one slightly shorter pushrod and tighten up the set screw as needed. That locks them both together. Handy for routing pushrods through tubing to the back of the plane.

I have typically just used dental floss and wrapped it around the two pushrods (one longer and one slightly shorter) to join them together. I then super glue the floss and the two parts are bonded to each other really well then. In the past I used epoxy resin to do the same thing. But nowadays super glue works great on the dental floss.

Years ago the Y pushrod was commonly used. One long pushrod was coupled with a second one and a Y was formed. You would thread two lengths of string down into the fuselage from the elevators on both sides. Then tie the string to the Y ends and pull it through to the back of the plane as needed. You could bend the pushrod wires as needed for smooth operation. Coupling the second pushrod on was done using copper wire and solder. But dental floss and epoxy resin or nowadays using super glue does the trick too.

Thanks for this very good tip. Appreciate your time.
I was searching Towerhobbies for the piece with no luck. I swear its made by Dubro or Sullivan. Youre right its just an aliminum block with three set -allenscrews locking the pushrod wires in place.

I have seen such a device in a World Models AT-6 arf. I replaced it with copper wire wrap and silver solder as whiskykid suggested.

When I put the three rods together and solder them I try to use rods with threads on them. I put the threaded ends together, wrap with copper wire and solder. The threads lock the rods to each other and the chance of them slipping is next to zero.

A couple of wheel collars do the trick and you can adjust them if you need to.

The proper name I think is a V-Tail mixer and they have them all over the place but are rarly used anymore. I think I even have one NIP and never used it.

Suggest you make your setup and tighten the three set scews.
Then take it apart and file a flat where the set screws made their mark.

Re-install and tighten the scews again on the flats.
If a screw becomes loose the rods will not get out of range.

Thanks for all the help gents.
Here's what i did. BTW, the 1st reason I did this was i didnt like the factory /oem elevator configuration of my Zero aircraft. It was causing uneven elevator throws.

Thats even a nicer setup. Looks like it absorbs initial shocks with its springs. :thumbup:

So it would appear - but the spring is actually there to keep tension on the socket cover (the white part). I have the same type of connector on my DLE 20's throttle:



Pulling the socket cover back against the tension of the spring allows you to remove the socket from the ball.
