Is there anyone still out there? I guess the list has gone even quieter now
that Oshkosh is on. But for any poor souls like me stuck at home still
building - any advice on this one.

Have just bonded in the wing lift/drag pins and the flap drive pin at which
point a few things became apparent:

1) the rear lift pin socket W26 has been completely redesigned and now comes
as three parts.

2) The whole of chapter 27 had been re-written to include this fact and a
hole pile of additional work to install tie rods etc. Good job a ruined a
lift pin and had to ring the factory for a new one otherwise I would have
been none the wiser.

What I now find is that the W26 lift pin socket on the port side 'bottoms
out' on the aluminium plates bonded into the wing root (onto which the lift
pin is bonded) before the pip pin holes align. There is about 1.5mm
discrepancy. I'm not entirely sure the lift pin hole has been drilled and
tapped perfectly horizontal. Any one had similar experience or suggestions.

I think it has been said before, but the quality control of the XS wing to
my mind leaves a bit to be desired.
