CA

[Bob Kane]

Yes, put the higes in and install the movable surface to the fixed surface before gluing. If you try to do one side at a time, say put the hinges in the elevator and glue them, then install the elevator to the horizontal stab, the CA will seal the porous surface material of the hinge and it will not wick properly.
 
I forgot to mention, use foam safe CA if you are working with foam core parts. You can use a pin in the center of the hinge to keep it centered while pushing it into the mating surface. Draw a line on the center of the hinge so you can verify it is centered before gluing. Take the pin out before you put the CA on.

Do you dry install both sides and then glue? Aileron and wing, elevator and stab etc.?

The glue should wet out the surface, add thin CA until it stops wicking into the material. Use a tissue or swab to clean any excess CA. Do the same side of all hinges. Clean any CA off the parts, turn over, and repeat on the other side of the hinges.
