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.
