Paul,
Positioning the W26 has been a head ache from a lot of builders. However, when
referring it to Andy (of Europa) he mentioned the following points and it is not
too hard to fix. Keep the pins as already positioned. Once the lift/drag
sockets(W26 and the front one, forgot the code) is positioned on the pins for
alignment position the wings to the fuselage at 2.5 degrees;

1.The holes should be no closer to the side of the metal inserts in the fuselage
than 10mm. Except for the bottom hole which can be a little less (up to 5mm) as
it is a positioning hole and not under tension.

2.If they are then you must reposition the metal insert inside the fuseluge wall
by taking it out from the outside, repositioning it correctly with flox, and
then cover with 3/4? layers of BID overlapping the fuselage skin by 25mm all
round on the outside

3. The front lift/drag pin must have that same 10mm clearance from the edge of
the metal insert. If not, then I, after talking to Neville(Europa), place the
socket at an angle to the insert to accomplish that 10mm clearance.

Talk to Europa about it to confirm the above is correct.
Cheers,
Tim
