My club has some problems with a Ka-8. It seems the gluing of the spar
and the torsion box has been done with better glue than that of the
ribs. It has been done with another glue type: dark brown for the
former (probably Aerodux), yellow/very light brown for the latter
(Kaurit?). The latter type of glue seems to fail easily nowadays.

However, metal structures are known to fail, too, and often without
warning, by metal fatigue. Normally, sailplanes are made over strong in
critical metal components, just to allow for this phenomenon, but it's
not foolproof.

Let me get this straight, you're complaining that the LP15's cockpit
is too big? That's a complaint I have not heard before about any
glider.

And yet, the Schempp-Hirth people are producing their "a" model
fuselage (Discus a, Ventus a) for that reason, some competition pilots
complaining that by making their cockpits too big (like the Standard
Cirrus), they were wasting possible aerodynamical advantages... These
fuselages are advertised for slim pilots not bigger than 1.75 m.
