No, I would not rip apart a new glider working perfectly.

Nor would I under any circumstances let an unqualified mechanic make
the matter worse - one who apparently thinks banging a square peg into
a round hole is a good thing. Looking at how the stabilizer cover is
torn and the bolts that were inserted are wrong - makes clear that
somebody hammed up the thing for some reason and want the manufacturer
to take the blame.

I would also not claim on a public forum that there is little
technical information in the manual when other owners have clearly
stated that is not the case.

People do stupid things in life. The glider is pretty banged up just
from the manhandling by the Aussies. Why we don't know. Maybe she
wanted the control forced to be made lighter and someone promised her
they could "fix" that.

There are a million reasons. But just because someone fiddles with
their new glider does not prove there was anything wrong with it.
People fiddle with their new gliders all the time. Only this time they
screwed it up.
