M&H announces NEW WINGLETS for the Ventus2 and Discus. The winglets
are designed by Prof. Mark Maughmer of Penn State University and the
Ventus2 winglets are expected to be available late spring 2012. Discus
winglets expected availability will be announced here later.

Monty, Heinz,
Please put me on your list of interested parties. My competition
season has a big gap in July - perfect for a retrofit operation! ;-).
Any idea of the retrofit cost?

Discus 1 or 2?
Have you spoken to the factory about getting approval for this mod in
Europe?
Those of us in EASA land are pretty much constrained to using the factory
winglets

I'm curious - since the image on the link appears to have an outward cant,
does this increase the measured span beyond 15 meters, or is more cut off
the tip during initial installation to account for this?
Or, put differently, while sporting these winglets, can the glider still be
fit between two posts spaced 15 meters apart? Or does anyone care about
that any more?

Re canted winglets increasing span: I recall a reported conversation
between a well-known competition pilot (WKCP) and purveyor of
modifications etc., and a competition official (CO), re some new wing
tips.
CO: It exceeds 15m span now.
WKCP: Not when it’s flying – the added dihedral from the wings flexing
reduces it to 15m.
CO: When you show me by flying between two posts 15m apart without
hitting them, I will let you compete with those.
End of conversation.

Note that the reference wing in the graphic is horizontal. Go look at
how much dihedral the tip panel has and you will see that the cant is
nowhere near as much as it looks in the graphic.
These guys have been doin' this for awhile and have been to a few of
these here rodeos.

I can personally verify that Harold Drew, scrutineering at the '65
UK Worlds measured the Standard Class gliders by opening two
hangar doors to marginally over an accurate 15,000mm and
required each glider to be manoeuvred through with wings level.
He made the same reply ('you can fly through the gap of you
prefer') when offered the same excuse.
The Finnish Vasama was significantly over span; the Team
Manager offered the explanation that the glider was so new the
wooden spars were still growing. Firm action with a plane to the
wingtip fairings made it legal, if a little less pretty.

The FAI Class rules are clear that the measurement is in the
"unloaded" condition, which is taken to mean that water, wing mass,
gravity and lift are all negated. That condition can be subjective,
but they give the example in the rule that it normally means that the
measurement is taken with the wing supported so that the trailing edge
is straight.
