A question for Mark Langford: The Dr Dean hinges you have used look like a really neat solution. However I have one query. How do you lock the bolt holding the MW3 Rod end in position? All the others have self locking nuts, but there is no nut to lock here. Peter Drake Hereford UK

Peter Drake Hereford UK ___ I just epoxied the bolt and made a little cavity in the foam and filled that with epoxy. For that bolt to turn it would have to break the epoxy bond from bolt to the spar and then turn that chunk of epoxy through the elevator fiberglass skin.

They came along after my time. Don Chisholm (who unsubscribed last week, if I recall) first gave us the idea in an early newsletter while building his first KR1. I tried to make it work but couldn't find exactly the right components. Dean tried harder and made it work. I'll leave that question for somebody that's actually done it to answer. Mine are aluminum but use oilite bushings (shown at http://home.hiwaay.net/~langford/kvs.html ). They are light and work fine.

It seems that epoxy is the way to go. I was wondering if Loctite on the threads would be acceptable.

Yes, the flox can be used for securing the head of the bolt so it will not turn or you can do as I did and flox the shaft of the bolt through the wood. I did not flox the head of my bolts. I also placed a large diameter washer under the head of the bolt to prevent any pull through or crushing of the wood. If the washer you use overlaps the edge of the spar, simply grind the washer flush. You may use Loctite on the threads if you wish but if you do, do not use the permanent type as some day you may have a need to disassemble the hinges. Plus, even if you do not use Loctite and have floxed the head of the bolt, there is no way that the set up will unscrew itself. Another thing is that when you glue the foam to the spar, you will also be gluing the bolt head then.

I am using them for my elevator, and rudder, but the ailerons? I have never seen anyone do that. Does anyone have any drawings or photos of such a design?

I like the idea of dr dean hinges. they are briliant! I know they are used on the tail but is it ok to use on the alerons and flaps? How many should be used if it is ok. jerry getting parts for a kr1.

There is absolutely no reason not to. I did not think to do that on my ailerons but if I had, I would have. I would put one on each end of the aileron and space five or six more evenly in between the two outer ones. Do the same on the flaps and I would think a total of three per flap would be sufficient. This is just my .02 worth and there is no engineering data to back this up.

Somewhere I lost something. What are Dr. Dean hinges? Thanks Kevin

These would also eliminate that gap on the bottom of the aileron when you use piano hinges.
