Probond,
Any hardware store should carry it. Canopy glue will also work well for hinge points and you can clean up with water!.

Countersink the hingepoints so the control surfaces will touch when they are installed and dry fit everything.
I use vasaline applied to the hinge pin and fingers with a toothpick and heat it to get the vaseline into the joints. Wipe off any on the outside.

Glue both sides at the same time and flex the control surface to make sure everything is lined up. As you flex the control surface the hinges will line up if they were fairly lined up to start with.

The Hitec servos are the best on the market. They draw less current than many regular servos while JR and Futaba servos draw much, much, more current and are more likely to overheat.

The coreless Hitecs are the best but will cost about $75.00 dollars, still alot cheeper than JR at $118.00 or Futaba at $139.00 which have less power, less speed, and more current draw.

You will have to CALL around for that price because it is below the manufactures suggested price.
