Does anybody have a drawing or picture of the
torsion linkage used to drive the ailerons in
early Ventus or the rudder in Libelle ?
Or can tell me what that's called ?

Thanks !

PS: It was used to avoid external bellcranks,
with their associated fairings and drag. It's
out of favor because it is problematic
(cost, weight, stiction, etc), and it turns
out the fairings add negligible drag...

Big thanks, also from Jud for whom I asked
the question, to all those that sent info.

Mega-Thanks to:
Brad, who emailed pics of the Libelle
rudder drive,

Colin Bryan from NZ, who emailed pics of
the Ventus a/b aileron drive nicely exposed
in a damaged wing.

Honorable mention to
Stanislav Poslušný from Czech Republic,
who mailed pics of the 304's rudder drive.
The 304 was the last Glasflugel design,
and the HPH version is much improved -
painted nice bright red instead of drab
blue-gray ;-)

Thanks also to a couple of folks who
emailed pics of the control-circuit
schematic from the manual (but you
can't see the skew drive in that pic).

You guys are great !
Thanks again,
Best Regards, Dave "YO electric"
