Discus 2a vs Arcus @ 200km/h - EGC 2013

Hi ladies and gents,

Here is a video made by Sebastian Kawa on ECG 2013 at Ostrów in
Poland.

This video presents final glide of his Discus 2a wing to wing with
Arcus flying at 200km/h. As you can see at this speed performance
of 20m span glider is no better than 15m Discus 2a.

And yet, the Discus2 has the same OLC handicap as the Glasflugel Mosquito...

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?

Mark Burton

People will be discussing handicaps and wing loadings and other topics, but I think this just proves what everyone has known all along: Kawa has magic "I get to fly faster than you" powers which transcend the laws of physics :-).

Hi,

Of course, the Arcus has a much larger fuselage than a Discus2a so its
performance at high speed will suffer as a result of that.

You don't buy a two seat, 20 meter glider for it's 200 kph performance.
How fast would the Discus go with a 180 lb passenger?

It was a D2a, so 15m. I suspect at or close to max all up weight, so to
comment on a later question in this thead, not carrying carrying a 180 lb
P2, but probably 350 lb of balast.

another later post, not carrying a 180 lb P2, but 350 lb of ballast.

Cant be 100 % sure but that does not look like a Discus 2a wing tip.

I think Its the same D2a that belonged to Mr.Galetto. It is is the Polish National Team glider, they also own another one, but strangely this one even being form early of production, is of lot better quality than the later production number ones. Interesting proof of that theory is the Lak 12T prototype beating the crap out of several Arcuses and Duo Ds XLTs after several days of competition.
