Standard Cirrus C-Hook

Any chance the larger is for a Cirrus77?

John,
Thanks for the link for the ADs and Technical Notes.
It is a great site.

This glider has been complied with for the the 1970 Tech Note 278-2.
The C-Hook is the same one shown in this Tech Note.

I have not been able to anything that mentions using this larger
hook and bearing.

The elevator connection for the Std Cirrus is idiosyncratic to rig, not
difficult to mis-connect (in my hands), and requires careful checking
before flight. *Not a place for second hand or non-standard parts. *

There's a chance that the larger part suits a Nimbus 2 as this is the same
set up as the the Std Cirrus but larger.
The Cirrus 75 uses a different system all together to retain and drive the
horizontal stabilizer using square drive dogs and a clevis pin arrangement
in the top of the fin.

Yeah, after I posted I thought about Nimbus 2, with all flying tail
like the Cirrus.

And the Janus.

Our Janus C does not have an all flying tail. and I do not remember this "C
Hook" on installation.

That would be because, unlike the "Janus", the "Janus C" does not have
an all flying tail.

I don't know what mechanism is inside as I haven't derigged either of
the Janus's I've flown (ZK-GLM and ZK-GSH).

Speak to your Schempp-Hirth agent of Schempp-Hirth themselves.
Schempp-Hirth were extremely accomodating with the tailplane bush
replacement kit for my Std Cirrus (and later winglets). Almost all of
their staff speak English

Also see the Std Cirrus website and its Forum - over 330 owners there.
http://www.standardcirrus.org/

For the tailplane diagrams from the home page select
'issues' from the radio buttons just under the web page title
then select
'elevator'

Bottom line - fit the right part and ensure that it is fitted/adjusted
correctly - control surface movement/measurements iaw the flight manual.

Good luck.
