Thanks for the translation and the other info. As an Arcus owner I
was rather disappointed! Was the Discus flying in 15m or 18m mode? Do
we know how the wing loadings compared?

You don't buy a two seat, 20 meter glider for it's 200 kph performance.

If you're an owner who wants to enter it in the European Championships,
I'd say you probably did.

How fast would the Discus go with a 180 lb passenger?

Even faster! All that matters is the wing loading and the polar. At
that money, the Arcus should have as good a polar as the D2 - it's
nearly 20 years younger. It was probably flying at a higher wing
loading too.

I didn't suggest adding 180 lbs, I suggested cramming two people into a
Discus. Surely you don't think two 180 pound people in a Discus would be
able to fly at all, much less faster than an Arcus? But to go with the
flow, it would not increase the wing loading, because you'd have to
remove 180 pounds of ballast. Contest rules, you know.

My I should have added a winking smiley face?
