Laid back flight position, *but not for huge / tall pilots perhaps, but
flys without any vice, and great "44" performance for the first all
plastic composite glider in the world.

Hmmm, glad to hear it's well mannered and comfy, but it's not exactly
the first plastic ship. The first *production* models (Ki Ba Vo
Diamant prototypes used wooden K-6 wings/tail...) used H301 wings, an
all plastic ship which was obviously in production before the HBV came
out.. which was then followed by the 16.5m, and finally the 18m
variant, which didn't come around till 68'... For all plastic, the 301
itself even came after the:

(actual first glass ship...)
Pheobus http://phoebus.vassel.com/site_page_2511/
BS-1 http://www.sailplanedirectory.com/glasflugel.htm#BS-1 and I'm
sure there were some others too...

The 18m variant was after the D-36 was, which led to the W-12 by 65

Even the Open Cirrus was flying by 67' , but I'm not sure if the
Kestrel 17 (Glasflugal 401) was slightly before, or after the 18m
Diamant in 68...

Still an early glass bird though
