The wing failure in Chip's aircraft was NOT flutter or anything related including structural, the wing bolt got loose do to Chip trying something new, but it did not work, so it failed and the wing came off in flight.

That aircraft was Chip's main for the F sequence, and he wanted to keep flying that one, that is why a new wing was installed on that airplane overnigt, who bught the aircraft later is a something I am not aware of as Chip sold all his airplanes there at the field after the contest was done.

I think it is very important to get the facts straight, and I can only help with the information I got first hand because I was there and are friends with Marcelo and Chip.
