Any thoughts on the Ka-8?

A lovely glider, utterly viceless and soars on a breath. It
doesn't penetrate very well into wind, so cross-country
ambitions need to be modest (though Karl Striedieck did
a 767km out-and-return in one).

Things to watch out for?

I can't think of anything other than the glue and the state
of its trailer.

Difficulty rigging?

Not at all.
