Bruce,
I thought the same thing, but thought I'd wait and see what he says about them. I think he means the control horns. Chad, if that is the case you don't glue the control horns on. You mark where they mount, drill a hole through the aileron for the mounting screws, and then use the mounting screws to attach the horn to the aileron. Make sure you screw the back of the control horn to the other side of the aileron.
