The wonderful joy's of rigging ! As Des has said there are many methods out there which are used . Through the wings is the easiest and less frustrating way to rig . i have tried this method before but was never good and the triming part until I learned this method which is done with twisted wire hoops and q-tips .
Start by drilling all of your holes , but don't drill all the way through . 6 or 7 turns of the pin vince will do .
Next step is using just a drill bit #80 and some fine wire from an old cord with the plastic strip off . Cut small lenghts . Bend this over the bit and pinch it as close as possible and twist the bit . You will end up with a small hoop . Trim off the stub on the end so the bottom of the hoop just touches the wing . Fill the hole with super glue . I use a medium glue for this . Placce the stub in the hole . The side of the hoop should face the direction of the line . Do this to all of the drill holes . Mount the top wing .
Now for the q-tip part . Just the same as stretch spure but using the plastic q-tips pull this to the sizn of tubing you are comfortable with . Cut small lenghts to about 3mm or less . Now take your line and slip on two of the cut tubing . Pass the line through on of the hoops and back thread it through the q-tip . Sinch this down to the hoop and just touch the q-tip with runny super glue . repeat to all of the others . Paint your line to what ever colour and same with the q-tip bits which are the turn buckles . What I like about this method is if a line does break . You don't have to redrill the hole and start over . and the line will pull to and angle you want .
This works well in 72 to 32 scale . it is more time consuming but the end results are well worth it .
