CA(cyanoacrilate), noun: type of super glue that bonds skin instantaneously, and everything else in three seconds
jk
good answers above, although I'd like to add that ca will not bond most metals(especially if it vibrates) for most wood to wood joints one of the best ways to glue is use an eyedropper to put a few drops of thin(if your not careful you will not only glue your work to the table but yourself to the work and the table and the bottle and...) then go back over it with med, the thin soaks into the joint to get a good bond, then the med really secures it. but like doc said, use epoxy on wing halves or other super-high stress parts, it's a little heavier, but make a better bond.

and always remember, ca+balsa=hardwood
