Dihedral canard ? Chrissi? I think that Nat would prefer that the

nameplate

reflected some other name
However in the pattern and talking to the tower what you say is very

true.

Vance1,
The dihedral canard has an interesting history. As related to me by

another

gentleman named Vance2, he was the first to adopt the newer Roncz

canard. The

original GU canard as implemented by Rutan had issues with bugs or

rain... it

lost lift. When Vance2 talked to Roncz about the "rain canard" Roncz
intimated that while doing computer simulations that 3 deg of dihdral

might

add a few knots as well as get the tip vortexes up and away from the

main

wing; improving roll rate. So Vance2 implemented the first dihedral

canard.

So although the Roncz canard is now standard, few have adopted the

dihedral

due to the 10% challenge to get 1% better performance. Seems to me Roncz

is

the greater expert in this case. As to the modification, it has been

tested

and flown. If no other improvement materializes it has proven to add a

small

amount of stability.
And finally, after a few encounters with Nat on other issues I don't

give a

rat's ass anymore what he thinks, it's a Cozy, it looks like a Cozy, it

was

built from Cozy plans, I paid for the rights to build it. No where in

those

plans or agreement did it specifically say that it must be registered as
anything else. Secondly, a rule has to be applied equally. While he has
condemmed planes with parts made by x-y-z company as "bastardized

ripoffs"

(x-y-z company president and I decided these should be registered as
"AeroBastards") and then a plane with those same parts wins Grand

Champion

and all of a sudden he's Nat's best friend and the plane is a Cozy and

gets

published in the Cozy newsletter.
Just from the recognition and safety point of view, the name stands.

I have always been mildly curious about how the canard tip vortices

affected

the main wing. If placed properly to pass over the main wing they should
enhance main wing lift.

Chrissi - Thanks for the timely and excellent response to my raised eyebrow.
sounds like a good case.It also sounds like your experiences witn Nat are
much
like mine. He almost threatened me with physical violence when I had the
nerve to confess that I did not think canards were my favorite
configuration.
The interaction between canard vortices and the wing was factored into
the wing design on Burt's largely unsuccessful excursion into the sailplane
world.  The wing was "cranked" at about that point of the span. I do not
know if Ronz was involved in that design or not.
