Well the Chiribiri isn't quite complete, but nearly there.  Cos I still haven't sorted out a image host here's a couple of film clips for you...
 
The first is a "walk around" of the C.5  ( https:// vimeo.com/ 412079449 ) and and there's also clip of the local Neighbourhood Watch ( https:// vimeo.com/ 412075421 ) coming home after having been out making very sure we're all observing the various distancing rules and that no-one is having any fun whatsoever:)

As seen the C.5 tips the scales at 9.79g.  I'm expecting an unballasted weight with rigging & trimmed prop. shaft v. close to , but a shade over 10g. The motor will be about 2g of strip.  The great unknown is the ballast, it's got a frighteningly short nose moment.

Sorry, you'll need to bolt the URLs together.

To a layperson that seems remarkably light and fantastic workmanship!
Self Assembly URLs are very suitable for the thread ;)

I'll grant that it's light, but it's no better than journeyman standard workmanship.  If you want to see really good, museum quality, stuff head over to HipPocket Aeronautics builders' forum and look for stuff posted by g_kandylakis, zk-aud, dputt and mkelly (and others). 

On the lightness front. Set initial ballast last night and as expected for a short nosed subject it needs a lot, some 3.4g or about 30% of built weight. This is going to give a likely AUW (inc. motor) of ~16g.  Which means endurance won't be as good as the Lacey (upthread) which has a lower wing-loading but it should still be capable of a decent flight.

I know they are an utter pain in the arse, but whenever I've embedded them in a {url} tag they don't render in the posted message.  Just pretend you bought them at Habitat/IKEA*. :)

Finally sorted out some image hosting, but the img tag isn't playing nicely with the URLs, or vice-versa.

Assembly complete.
Built weight  10g
Ballast          3.4g
Expected initial AUW  15.5-16g

Now all I need is a bit of very calm, dry weather to trim it.

Careful, Kim. Your sarcasm's showing...

Ah. Yes.  Shows you how long since I last mucked around with image linking doesn't it?  Put it down to old age and general idiocy.

Not my flight of fancy. Far more amusing and interesting than anything I could do and deserves wider circulation.

Read the opening post if nothing else.  It will explain the video links below.  I defy you to not have a silly great grin on your face after you've watched the films.

What an absolute delight. I watched the first four a week or so ago and it's all just plain (plane!!) wondeful.

After Pete's lovely films, back to The Potter's Wheel...

A long time ago (summer 1973 if you must know) a young (difficult to believe, but yes he once was) Lurker built his first ever flying model. Keil Kraft's Minimoa.  It didn't fly very well, but it did fly so here we are again.  This is a scaled down version.  The world and her brother have created any number of 100" span RC Minimoas for slope soaring.  I wanted one for which I had house room, about 34" span, for Free Flight bungee launching. So after some considerable faffing around in Inkscape redrawing formers, rib profiles and whatnot I've got a plan.  All that remains is to see whether or not it's buildable and will fly....

My favourite glider ever. So beautiful.
I think you'll find it's a bit more complicated than that.
