Our club has a G102 that is a problem to rig unless the following points are
observed--

1. The vertical stabilized must be absolutely vertical and held that
way--usually by a person but a jig could be made. The person doing this must
be made aware of the importance of this task, as their attention will wander
otherwise.
2. The 4 wing pins must be very well greased--if not, they cannot push the
spring "fingers" inside the fuselage fitting aside and the friction will
prevent the insertion of the wing. This is the usual source of difficulty in
our experience.
3. The "olive" bearings that the pins on the end of the spar must be lined
up before inserting the wing and watched to be kept that way. The rear one
(left wing) is hard to see-often impossible, but keep trying. The right wing
goes in first so you can see the one you are chasing. Pay attention to
dihedral.

Good luck

I recently acquired a Grob G-102 and am still struggling with getting
that second wing installed during rigging.

I'd like to hear from any G-102 owners out there that are willing to
share their tips and tricks on setup, especially concerning getting
that wing lined up and installed.
