Hi Steve and Pete
Just wondering where you got this 5 hinge requirement from? It may have
applied under the old Australian ABAA (Amateur Built Aircraft Approval) but
I don't recall it. In any case the ABAA is now obsolete and replaced by
Experimental. Under the latter, provided you can convince
Steve,
If you're wanting to get an Australian CoA for the aircraft then you
might have to refit to the Aus. standard of 5 hinge points along the
Horizontal.
Cheers.
Pete.

Sorry, can't resist... What is it that we "know now about KR hinges"?
Sure, Dr. Dean hinges may be better, but KRs have been flying for years on
the original hinges and I have never heard of a failure. Please explain
where this new knowledge comes from.

My hinges have about 1200 hours on them and 23 years and seem like new -
no looseness, no creaking, and I don't even lubricate them. I suppose I

And by the way, three for the rudder and four for the elevator should be
plenty. I'm sure you've seen Dr. Dean's stuff at

Make that FIVE for the elevator, although I wouldn't be surprised if 3 would
work fine, but four would be awkward. The bellcrank needs one, so we're
talking odd numbers. I'm crawling back in my hole now.

Netters,
I just used the plans for the Dr. Dean hinges and they are sweet to build.
Cost about 10$
per hinge at spruce. Go buy 'em.

Chris,
The Dr. Dean hinges are far superior to the stock C channel hinges. Do
not even think about the stock hinges, use the Dean hinge method.

The plans call for aluminium hinges. There are two types of hinges,
extruded and rolled. The
They are extruded aluminum and you can get them at either and I would not

I don't guess any of us actually answered your question though. The
aluminum hinge material called out in the plans is 1 x 1 x .125 channel and
1.25 x 1.25 x .125 channel. I should also point out that the new airfoils
designed by UIUC were for the wings. The airfoils shown in the drawings are

But that's not for ailerons, it's for elevator and rudder, although I
