All

Have just finished fitting the fwd W27 and aft W26 wing sockets to the fuselage
and everything looks good. Wing angle is good on both sides and checked at 
mid-point
and wing tip.
Fwd aft sweep measured at several points is good. String from each wingtip is 
parallel
with the spars.
Both wings assemble easily and both main spar pins fit with a firm push and a 
bit
of effort.
However, when assembled there is a small amount of fwd aft movement at both 
wingtips
relative to the fuselage.
As far as I can tell this is entirely due to the movement of the parts making up
the aft W26 socket. The pip pin is a good fit and the small amount of movement
is between the W26C barrel and the W26A body.
It is a small movement but over the span of the wing is obviously magnified.
I have checked the gap between the fwd W27 sockets and the wing root rib and the
gap is 0.8 to 0.9mm both sides.

Should I be worried about this fwd aft movement.

I have no wing root fairings on at present and guess this would help limit the
fwd aft movement when finally fitted.

I hope I am worrying about nothing but all opinions, views appreciated to put my
mind at rest.
