Hi all, does anyone have an alternative to both Sig Stix-it and their nitrate dope. I have their fabric but can't find the adhesives. So hence the ask for advice. Any help appreciated.

Gents, how to I calculate where to place the holes in wing ribs to except a wing tube as the dihedral changes. Long story short. The model I wish to build has a built up centre section and foam outer panel wings. I wish to convert the wing to a whole built up one with detachable wings. (ie, three part wing) My problem is, I don't know how to calculate where the wing rib holes need to be in order to take a wing tube as the dihedral changes. Any advice welcomed
