Thank you everyone.
Lovely work, Prze 
Forgive me if I've missed this, but can you share how you made the jig and was it from plans or using the kit part as a form?
Cheers,

The jig to control the dihedral was made using the scale drawings from Windsock Datafile.
The holes for strut pins in the upper wing were also retraced according to those drawings. Having these drilled, a couple of weeks later, I have just measured the distances and made the fake upper wing centre section jig from the kit part :-) Hope this makes sense ;-)
And in the meantime I have rigged the wing cellule and started attaching the undercarriage.
