I second the Hinge Points. If you buy a drill press, you'll get them dead on every time and the drill press will be one of the most useful tools in your shop. I use hinge points whenever possible.
How to Install Robart Hinge Points
I like the idea of using the d.p. for drilling but a question: they would have to be drilled PRIOR to attaching/becoming part of the control surface. Is there a surefire method to use in ensuring that the holes are placed in the correct position on both le/te of the relevant part? Some pieces may have to have ends trimmed, etc which would cause (me anyways) alignment problems.
