833 lbs is fantastic. My XS Mono/914/Airmaster came out weighing 50 lbs more!
Thinking
about that lighter mono wheel and brake to shave off, how much was it?

>> Graham, Are you sure? You usually are, but competition gliders are produced
with amazing attention to their finish - gel coat rubbed down progressively
to 2000 grit and then polished with hard wax. We share their laminar flow
aerofoils
which are said to be highly sensitive to surface imperfections.
