MorganS:

I stand corrected, the engineer DID come up with the modifications
required to make the wing work in High stress air racing environments.
The request for the source of the information is on it's way.

And I will be buying the plans for the Sonerai, but not for the
fuselage. After looking at Cassutt and Renegade plans for the
specifications, materials and such and looking at what Ib Hansen did for
his aircraft, I think I am in the correct ballpark.

It is wise that the people on this newgroup not advise. I was not asking
for advice from the newsgroup. Only asking for a source of study plans.
And someone was kind enough to supply the name of GPASC. That is enough.

Several years ago a Sonerai lost a wing making a high G turn during an
air race conducted by the Formula V Air Racing Association, resulting
in a fatal crash. The Formula V group then hired a professional
aeronautical engineer to conduct a design study and and a wing
strengthen modification was the result, which was made mandatory for
all racing Sonerais. You may wish to contact the Formula V people for
details : http://www.formulav.com/


I think this post is very telling, in why you have not had any other posts
answering your questions.

It is a very risky procedure, to start major design modifications, or
substitutions to a critical structure, like a wing. If it fails, you are
probably dead.

No one here is likely to be very comfortable having any part of advising, or
being an accomplice of such a substitution of such magnitude and scope.

So although I think it is a bit of a cliché, If you have to ask, you don't
know enough to be asking.

My best advise? Build it as drawn, or find a plan that has what you want,
in the original design.
