Insert the hinges and control surfaces in place then insert the flex tip down into the drilled hole and apply the CA liberally . The "hinge" will wick it in and down and attach it to the wood.
I'd rather use nylon hinges and use small straight pins to "pin" the hinges in. Once they are cut/trimmed they are hardly visible.
The hinges I like to use most often,when/where I can are the hinge points
Ditto ! For years I used nylon hinges, both glued and pinned it. Would not even think about a cloth hinge, but then I observed more and more folks using them, thus I decided to give them try. I used the same method of drilling a hole into the middle of the surface, where the hinge will be placed. While I do not use a flex tip, I know that I am getting very good wicking thru the drilled hole.
Have never seen a cloth hinge with a string attached, but right now it would only make sense that it would be for wicking. Could just be a new idea, but this is the first I have heard of the string. Personally, I think you would get better wicking with a drilled hole. Seems like the balsa and hinge really soaks up the CA with the hole method.
Since I first tried the cloth hinges I have not had a problem, with not one failure.
