Mike,

I was a kid around Texas Soaring Association whan the Sisu was being
built. The performance was 38/1 as I remember. The speeds and so forth
I have no clue... sorry. I sat in Al Parker's Sisu when it was being
built and made swishing noises. My brother Jessie delivered several to
their owners after building the trailers and most of the glass parts
(leading edges, nosecones, etc.) Unfortunately, a lot of that knowledge
passed with him several years ago. Wish I could be more help.
