I've seen a photo of a Std Cirrus where that
was done. Just the pylon, no struts. mid 1970s.

I attended a talk by Gerhard Waibel about 10
years ago (or maybe 15 years ago).
Among other things he talked about the wing
fuselage intersection drag. His idea was to
raise the wing on a thin pylon more than 200mm
above the fuselage and then support the wing
with struts! I thought that was really
reinventing the wheel. But he was right. Here we go.

Yes, as Bernard said there are other composite
sailplanes with high wings. Phoebus C, Std Jantar 2/3, ASW 15.
However have another look at the Mu 31, the
fuselage cross section in particular where at
around pilot shoulder height it necks in. This
is more like the Weihe, Meise (Olympia),
Slingsby Sky, early Slingsby Skylarks etc.

Not just new wings (same sections though ) but
extensive changes to fuselage also so I think a
new model number is warranted. Better for sales
anyway. Wouldn't surprise me if the EB29R is
further modified and becomes the EB30. Looking
at the R wing at Benalla it didn't really fit
the old root fairings on the EB29.
Funny thing is some of the wooden gliders of
the 30s, 40s and 50s had similar wing locations
and mounting of the wings on a pylon integrated
into the fuselage. Didn't have the fancy wing
root design as they didn't have the CFD codes or computers then.
Somewhere I have a paper on the Mu31 where they
say they hope to get 6 to 10% drag reduction
with the wing location. We should know soon as
it won't be hard to find a good ASW27 and do comparison flights.
Before anyone gets too excited this is all pure
speculation on my part but if the comparison
tests show they are getting what they wanted........

Hearing that this will be the glider that
combats the V3 & JS3; new wings for the very
popular ASG29, the R is for Racing - perhaps a play on the intimidating EB29R?
"ROCKS" ?
Looks like Butch had a good time in the V2 aswell.

what does that mean??
