Grob G102 Setup

Well, I own a 102 Std III and have never had any real trouble with it,
but I think that the the most critical points are 1) having the right
spar position marked on the bulkhead and 2) having a 1-man rig. The
1-man rig allows the weight of the wing to be supported at the center
of the wing, so that there is no vertical load being supported at the
inboard end. Those loads are being supported by the pin fittings that
you are trying to get to slide togethor. They will slide better if
they are not under load.

The frustrating thing is that they all look just fine but the wing
will still refuse to go in. I have tried (due to frustration) to wiggle
wing fore and aft and up and down but that never helps at all

Install the right wing, use a support a little inboard of the middle of the
right wing (near the wings CG). When you install the left wing stand at the
leading edge, and have a helper at the trailing edge. Support the wings
weight while you slide it in (use your right hand ). If everything is
aligned but it still doesn´t move, tilt the fuselage on its dolly very
slightly (like a rocking motion) with your left hand to make it go together.
A VERY slight, hardly noticeable back and forth motion on the left wingtip
can help, too.

Once you and your helpers have some training, it isn´t harder to assemble
than any other glider.
