Not a bad idea to check that your ship is tracking
straight, I test flew a 20 that would head for the
corn field on every flight. Walking it back from my
second aborted takeoff, I noticed it wouldn't keep
going where I pointed it. Did some checking and found
the factory installed tail wheel was a good 10 degrees
off center line. Tail skids are often reinstalled incorrectly,
also.

I wonder if you have the same problem I had with my
H301 35 years ago. Its
main wheel was not directly under the center line,
so when the wing runner
leveled the wing and then let go of it, one wing would
immediatley drop to
the ground. When this first happened, I thought one
wing was heavier than
the other; but this was not the case. A closer examination
revealed an
offset main wheel. The quick solution to this problem
was to tell the wing
runner to find the balance point instead of holding
the wings level. If
your main wheel is directly under the centerline, and
the wings don't
balance when held level, one wing is heavier than the
other; this can
happen if a repair was done to one of the wings.

Since 3 month I am proud owner of a H201B with 17m
wingspan and
'Speizklappen'. The glider I owned for 4 years, before
i bought the
Libelle was a Astir CS77. I like the handling of the
Libelle very
much, the only point I really have problems with,
is that the Libelle
loves to drop a wing at the beginning of aero tow.
Every take off that
a friend or me made with the glider was close to a
aborted take-off.
Other Libelle Pilots said, I should try to open the
air breaks for the
first 100m, but none of them owns a 17m version, which
has extra
weight on the outer side of the wing because of the
wingtip extension.

I am not used to this wing dropping by the ASTIR so
I hope I can get
some additionell advice here.
