As allways, Minn's advice here is true & sound! I have used the drilling of a small hole method & it worked extremely well. The CA hinges I was using had a small slot cut into the middle of them anyway, & the drilling a hole was a tip in the instructions that I chose to take the time to use. It also had me using the pin to center & create an equal gap along the entire hinge line. I simply put the hinges & control surfaces in place with the pins in the small slot of the hinges, then using a pen marked a small dot at the center of the hinge slot on both sides of the surfaces to be hinged ie. wing & aileron. Then I took it back apart & using a very small drill bit I just hand drilled the tiny holes about 3/8" to 1/2" deep into each side of each hinge spot. Then put it all back together using the pins for gap alignment, and as Minn said, used no CA untill it was allready to be glued at once. I used very thin Zap CA & squirting it into the tiny holes I had made that matched the slots in the hinges, it just flowed right into the wing & aileron, then flipped it over & repeated myself on that side too. All of it wicked together at the same time, and it was very evident to me that I was getting a sunstantial amount more of the CA down into the hinge wing & aileron than I ever had before without the tiny holes. In just a matter of a few seconds I litterally could not budge that aileron. Because of the pins I had a perfectly even tiny gap the distance of the control surface. I'm sold on this method & it is the only way I will install CA hinges from now on. I this info helps.

Merry Christmas!!
