scale hinges
 

Anybody know of a source for true scale control surface hinges? Before I drag out the brass and solder, just wondering if someone, somewhere has already done the work for me:) Looking for 1/4 scale rudder and elevator hinges for Cessna. Already have flap and aileron covered.
Something like this:

Somebody got to answer this.....I hope....................

It looks similar to some of the brackets that Proctor sells. But the real issue is finding something at the very exact size you need on your model -- so I strongly suspect you'll have to get out the brass and solder. ;)

MECOA has the CB line of hinges. Maybe some of those could be adapted: http://www.mecoa.com/cb/horns.htm

Most likely, you will need to custom build them. You can use some combination of aluminum sheet, brass/aluminum tubing, G10, and piano wire. I'm currently working on hinges for the flaps on a 1/7 P-51.

I'd given up hope on this thread. Those hinges have potential; I'll order some to play with. They look heavy duty enough. I was resigned to using the biggest Robart hinge points, but on the other big plane I have with them, several have broken at the pin, from vibration, I guess. It would be nice to be able to remove the control surface for repairs and maintenance without an act of Congress or having to gouge out the hinges. The hinge pockets that Robart make would be okay, but I don't want the little holes for access to the set screws, and the size hole needed for the pocket would potentially weaken the hinge line spar.

Thanks for all the ideas, guys. I thought about the Mecoa hinges, and looked at some of the Proctor hardware (the measurements are real close to what I need), and got some ideas of what might work. I'm gonna mess around and cobble a prototype together and see how it works. My idea involves making the hinges so I can insert a piece of 4-40 rod from the end of the control surface through the hinges, and then secure the wire. I've seen it somewhere before, but don't remember where.

The other thing I need to consider is, each elevator half on the full scale only has two hinges, and the rudder only has two. I have stiffened the hinge spars with 1/8 hardwood the width of the spar (also gives something for screws to bite in), so I feel that two hinges is enough. What do you all think?

Check out my Ray Torres T-34 build for some scale type hinges & controls, I used on it. The hinging and acuation starts at about post #21.

I made the hinges on the tail surface of my Beaver and PC-6 with plywood and brass tube. You can see it a little bit on this pics : https://mraerodesign.securicom.ca/fr...pg&ProduitID=2

They are removable and very strong. You can download the Beaver manual the see how they work exactly and how I install it on the model..

I use 1/8" thick plywood (5 ply aircraft grade) on each side with 1/8" balsa on center to get a thicker hinges assembly.
