Well I timed myself hinging the last plane I built, a 50cc Sukhoi which is typical of any of our planes. It took me 1 hour and 10 minutes;

30 minutes to prepare all the parts by taping across each hole, clean out the hole with an exacto, and slit the tape along the V edge.
15 minutes to glue the hinges into one side. I don't count drying time.
10 minutes to attach the mating surfaces
15 minutes to pull the tape away, put a drop of oil on each knuckle, and clean up.

It makes things go a lot faster if you have all your stuff out and prepared; blue masking tape, xacto with a few spare sharp blades, gorilla glue or probond polyurethane, toothpicks, small paper cups.

You should also make some kind of a stand to support the parts while you are working on them. Just a piece of cardboard with some slots cut in it to hold the ailerons/elevators and rudder while the glue dries. Nothing fancy is required.
