There are several versions of Titebond. The original (#1) is the best all around glue to use. Titebond #2 and #3 have uses if water resistance is needed (such as flying the plane in your Avitar off water). If I'm in a hurry to get at structure built a very small amount of CA is used to to hold parts in place while the main gluing is done with Titebond. An animal syringe and large bore needle (blunt the tip so you don't stab yourself) is useful for applying small amounts in the correct place. Titebond also produces one of the best polyurethane glues. It doesn't become brittle like some. For large sheeting projects (sheeting foam wings or other parts) it is hard to beat. For laminating parts it's best to avoid water souluable glues like Titebond. Polyurethane is good here as is epoxy. I find the epoxy to be a bit messy however. Contact cements have some uses but there are some that have all the strength of day old chewing gum after a short while. Weldwood is a good one to try. Make sure to try a sample so you don't melt foam or other parts. All Polyurethane glues have a short self life once opened. They set up by chemical reaction with water. Even the moisture in the air is enough to set the process off.
