What’s this called?

[EGB 953]

I need one of these so I can join two separate elevator surfaces. Any idea what it’s called? (See attached image).

Would a suitably sized electrical terminal block cut to length do the job?

An abomination.

 

VQ's instructions for a model that I have simply refer to it as a connector.

 

I bought a model 2nd hand that did something similar with a hardwood block.

 

My recommendation would be to use two mini servos, e.g. HS-82s (which is what I did in the VQ).

Model Fixings (modelfixings.co.uk) sell them and call them dual push connectors.

Lump of wood, drilled for wires, and locking bolts. Cheap too. 

[Paul De Tourtoulon]

Or three of these on a plank or metal strip.

I use the 3-way metal terminals from an electrical celing rose (see pic). Cheaper to buy than special 'dual push connectors', and more solid than using plastic terminal blocks. I then encase the whole assembly in epoxy once adjusted and tested.

Aerobatic models often use a ' forked pushrod '  made by bending both wires  in to meet the central pushrod then binding and soldering.    Less chance of an elevator failure due to a loose screw?

That makes sense or the suggestion of separate servos, this is for a small plane (25) so not expecting too much stress.  My soldering is pretty bad so the risk may be worse that way.

I don't mind those connectors, pretty sturdy and you can can give the studs a good turn, used on quite a few artf's I've owned and never failed me.

[Paul De Tourtoulon]

This is what I do when using carbon rods that you can't use screws on.

[Brian Cooper]

Forget "bodge" connectors. . Use two servos. 

[Nigel R]

I'd probably bend the ends of that wire over at 90 deg, glue / bind them to a hard balsa block or short length of hardwood dowell, then bind a third short length to go to the servo. Nylon thread, epoxy, some scrap wood, would take only a few minutes to do.

 

 

Certainly permanent enough for a 25 size airframe.

 

Effectively, a (very very short) dual pushrod - which were common (as kc noted) on old 60 size aerobatic airframes in 70s/80s/90s.

 

Two micro servos also works fine, but the single standard servo install is already there.

This looks a pretty practical option and your explanation is much appreciated. getting two elevators to be perfectly aligned might be very difficult though, any suggestions on how i might go about it?

If you get the connector close ennough any fine adjustments can be made at the clevise on the elevators ? 

[Nigel R]

As ED says. I've assumed there are adjustable clevis at the elevator end of the pushrods.

This is a fantastic forum - to have access to the collective wisdom of you all - it is greatly appreciated.
