OTOH, although I used to think that the CriCri was an incredibly cool

look like a "Mil-Spec" item. This is mostly because, although I do admit
that I have never personally seen a CriCri,. I seem to recall reading a
lot
of the skins are 0.010 aluminum. (Cringe)

I have a set of the CriCri plans, and I have to say that I'm pretty
impressed with the drawings and the general instructions. I wouldn't
buy them from pirates such as this guy, but they are worth having if
only for their guidance on working with light-gauge metal and mixing
metal and Klegecell or PVC foam.

I skimmed the plans and didn't find any references to skins thinner
than 0.4mm (0.016"). That's a pretty typical skin thickness even for a
lot of Cessna parts. I know that Aeronca ailerons are riveted up out
of a lot of .016" parts including ribs, spars, and D-skins.

Thanks, Bob K.

Well, I was concerned that I may have misremembered--and did. :-(

It's no surprise that the plans are well drawn, as M. Columban is/was an
aeronautical engineer.

I, too, prefer to have true, licensed plans. However, if the licensed plans
have indeed become unavailable in my country because of a tiff involving a
previous commission agent, then anyone who genuinely wishes to review the
design appears to have little choice. It is really none of my concern
whether M. Columban "shot himself in the foot" with an excessively durable
agreement with a commission agent or is simply, as the Brits might phrase
it, "in a towering pet!"

Just my opinion, and of admittedly modest value...
