Normally a thin piece of wood/fiberglass would be glued to the flange and that is covered.

i guess that is a better solution - I did contemplate it but the flanges are very narrow (3mm) on mine.. and now I've already glued the spoiler in place at the right (wrong) height so if I glued a piece of wood onto the spoiler flange it would now be too high, duh oh.... ah well, i will know for the next wings i make with spoilers !Last edited by neilk; 06-04-2018, 01:44 AM.

If you give some exact measurements to me then I can cut some lithoplate to fit onto you spoilers. Lithoplate is very thin and pretty stiff. I can even paint the top side white and have them ready to be epoxied in place at Horizon if you plan attending that aerotow.

Neil, sorry for the late reply. For some reason I don't get email notices on this thread. Very annoying. I glued my spoilers in after covering the wings so the covering is lapped over and down into the recess and then the spoilers set on top of it.

I found a way to fix the annoying lack of email notices on this thread...... get on the site and check it each day. Just sayin...Len Buffinton

Finally the new wings are complete :-)
The wings are at 3 deg dihedral, so I had to make hard balsa shims (since I didn't offset the root ribs). These were
painted with dope to strengthen and then glue to the ply root ribs, and then I covered.1 PhotoLast edited by neilk; 08-19-2018, 11:39 AM.

hi all
I finally completed the electric conversion on my Cirrus. If you are interested you can read the log here.
Also here is the log for the aileron conversion I did a while a go
cheers

Hi Ingrahal - everyone
This is my first post on Scale Soaring. I see that this thread has been quiet for 9 months. But - hey - what a great project! Maybe my post here will get things going again.
My interest here is multiple;
ONE. I have a Graupner Cirrus which I built in 1986. Except that it actually isn't a Graupner Cirrus. In fact I found the fuselage shells at the back of my local hobby store (now long gone, sadly). I had always lusted after a Graupner Cirrus during the 1970's - but could never afford one! I had a tiny photocopy of and outline of the glider and I scaled it up so that I could scratch build the flying surfaces. The result was a half decent 2-axis model which flew quite well except that it was very twitchy in pitch. That model hasn't flown for 30 years now... With Covid-19 causing lockdown here in the UK - I thought I would get the model out and completely refurbish it bringing it right up to date; Change the dihedral to 3 degrees, add ailerons and Schempp type airbrakes, re-paint and re-kit with 2.4g radio gear. The plans are now readily available on the internet - something I wish I'd had in 1986. So that's how I found my way here - when I searched "build Graupner Cirrus". Great stuff!
However - I have ended up with a lot more work than I was bargaining for. On examining the plans I was rather shocked to find that the stabilizer(s) I had built in 1986 were less than half the size they were supposed to be in the model version! I had taken the outline of an actual Open Cirrus, not the model. That's why the darned thing was so twitchy it's a wonder it flew at all. SO - I have rebuilt the stabilizers (I have photos if anyone is interested). Also on my 1986 version - I built it with an all-flying rudder, as I reckoned that a silly little half-sized thing wouldn't shift that big 3 metre wing. In re-kitting the model I am re-building the fin and rudder to the Graupner model plan specification. (photos available). Again - I was rather shocked to discover that the fin & rudder were all-sheeted in the Graupner model! On my 1986 version I had a simple open frame-work with nylon covering. I am in the middle of rebuilding the fin & rudder. After looking at Ingrahal's tratment of the fin/rudder, I think I'll use plasticard 0.5mm rather than balsa sheet. I will be lighter and blend to the fuselage better/easier. This is turning into a complex project and I haven't even started on the wings yet. If anyone has any ideas about how to speed this up - I'd like to hear them!
TWO. In fact I had a REAL Schempp-Hirth 17.7m Cirrus for 2 years 1992 & 1993 (photo attached - glider 782). I have 200 hours on type. In fact - my main passtime these days is flying my DG800B self-launching sailplane (G-CLSZ "44") - which I have just over 200 hours on. I got into real gliding from model gliding - but I am still a modeller at heart! As a pilot at Lasham - the worlds largest gliding club, I have access to prototypes of virtually all european gliders ever made. This is because Lasham is home to the Gliding Heritage Centre - a historic collection of vintage gliders http://www.glidingheritage.org.uk/
If any of you scale modellers would like any photos of real aircraft to work from - then I'm sure I can help you.

hi all
well I did finally maiden my electric cirrus and it survived ! Then the pandemic arrived so it's been waiting patiently. However, with the
very excellent help of a local friend (who helped me do the electric conversion), I now have a rudder that does not flop all over
the place. We replaced the floppy bendy push-rod with a pull-pull line system. Now 1) I get full throw, 2) it's symmetric hooray
and 3) I can't wiggle the rudder all over the place. Here is a little video
cheers

Hello Arup, lenb - everyone
lenb - when I saw your lovely model I thought it was an IS-28. We did have an orange IS-28 here in the UK for a while. I think I'll stick to orange, oh - and self-launching!
Arup - Did you see this: https://www.youtube.com/watch?v=nSHugyLm8u4
My Cirrus stabilzers are virtually complete;
It's coming along!
Meanwhile - I found some photos to work from from way back of me flying the Cirrus; 1992
Interior shot. Very basic panels in those days - no GPS/moving map, no nuthin!
In the years 2012-2015 I had a DG-200 15m G-DADJ "58". Here;
Cool huh!
Again - if anyone is interested - I can supply significant detail for your scale project, if desired.
I got into the real thing from flying scale model gliders. You guys flying big 3 metre plus ships launching by aerotow would find converting to full-size a snap. Also - for the price of some of those incredible models - you could easily afford to buy and fly a real glider. Jus' sayin'!
And finally - for those of you who may be interested - here is a video of some of the wonderful fun that can be had flying flying full-size. You should try it!!!
Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.

Martin- thanks for the info! I have seen those and even have a DVD movie about the fellas and glider! I would like to obtain a close-up of the fabric (with a mm ruler against it if possible) and have some printed. My color vision is terrible so it would be nice to know the color(s), too! My other glider project in formative stage is one of Neil Loving's gliders. I never knew he was a glider guider until seeing photos and line drawings of them in a recent edition of Vintage Glider News. I think it would be a great tribute to a fine man as it would be to the fine men who envisioned the Colditz Cock escape!
