Here's a method that works for me--- I look carefully at the kit to see if the main supporting struts can be glued to either the lower wings or upper wings, or to the fuselage-- whatever makes sense. I then take those main supporting struts and drill a .05 hole in the end of each strut for a length of fine brass wire. I then drill corresponding sockets into the wing or fuselage. I usually give the assembly a day or two to harden. I then place the rigging into pre-drilled holes in the lower surfaces or upper surfaces, whichever makes more sense. I then carefully attach the top wing, again letting it set for a day or so. When the wings are firmly attached, I place any additional struts, usually there is some wiggle room to slightly bend these. For example, I might glue the two outboard struts and the two inboard struts to the top wing of a SPAD XIII, then glue that assembly to the assembled fuselage and lower wing. I run the rigging through corresponding holes in the fuselage and lower wing. Then I glue on the upper wing, saving the intermediate interplane struts to be added after the upper and lower wing are together. It really depends on the engineering of the kit. Sometimes along the way, I use a very small drop of CA glue at the strut/wing joint--you can even do this before the styrene cement sets. This will give instant firmness to the strut/wing joins. Hope this helps.
