Also, it's not a mistake to put CA on both sides of the hinge. When I am installing CA hinges I will put the hinges into the surface and the control surface, and then position them to where there is as little gap as possible. Then I will deflect the control surface as far in one direction as possible, then apply CA the hinge in the opened up gap. After all hinges have had CA applied to them I will turn the surface over and repeat the same procedure on the other side. Once all is done flex the control surface back and forth a few times to loosen it up.
