Standard Cirrus C-Hook
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.

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. Gavin Std Cirrus, CNN now G-SCNN, #173 LSV Viersen, Keiheuvel, Belgium |

Randy,
I see you have already been active on the Std Cirrus forum and have taken my advice before I even posted it! My only observaton is that you appear to be quoting a US registration number. The number that Schempp-Hirth (and tehir agent) will be interested in will be the glider serial number which is stated in the glider log book/flight manual and on the small aluminium Schempp-Hirth registration plate on the inside of the fuselage. In German is is listed as 'Bau Nr.' and then 3 digits (possibly 2 if yours is a very early one). Grob and some other manufactures bulit Std Cirruses under licence so if Schempp-Hirth did not make your glider you need to tell them that. Be aware that the wings and tailpane will also have 'Bau Nr.' on a very small plate which may be different from the fuselage/verall glider serial number.

Gavin,
The Serial number for this glider is #9. This is what is in the cockpit, aircraft log books, original Bill of Sale and on the Airworthiness Certificate. It was built in 1969. |

The bearing size for my original C-Hook is approximately 14.15mm.
The newer/larger bearing size is 19.00mm Randy On Sep 20, 7:42*am, JJ Sinclair wrote: Chris, What size do you need in mm ? JJ |

Hmmmm,
All 3 of the birds I have in the barn are 19mm, you may have a problem in getting SH to come up with what was an early change to the design. I'll take a look at the elevator side to see how much of a hassle it would be to change both sides of the hook-up. Another poster said you shouldn't consider "used parts". My response would be; What do you think a 39 year old sailplane is, if not a collection of used parts flying in close formation?
