clamp control horn for elevator

These guys make THE best servo arms around, tried loads during my 10 years of kit building for customers and these were better than anything out there, they do a threaded through horn which the link shows that might suit if you put a washer or plate on the other side and a nut or the twin peg glue in ones are rock solid.

The arms with a Y design are so strong and hold the control rod at both sides so never going to twist or snap.

Hope this helps, this is a little gem of company.

Dreamworks has some of those. I just saw them on the website but dont think I saw a double.

Use robot parts by a company called Actobotics. They are easy to find at robot suppliers. Servo City also has them. I considering them for the stabs on my F-105 project.

Get one of these hubs and bolt it to the arm below. They are like erector set parts and all fit together. The bore sizes are common sizes. 3/8, 1/2" etc.

Gary,

What a great find - amazing web-site. I'm sure I can find a use for some of those parts on my Bucc - weapon bay pivot bearing blocks immediately come to mind!!

Here are some parts used to put together a stab system I am looking at for my F-105 project. These photos came from Fighteraces in the UK who gave me the idea. All Actobotics parts except for the aluminum base.

Hi, I know this is a struggle for a lot of people. If the clamp doesn’t have any instructions you can search on the internet.
