For model use the regular Titebond is the preferred glue. Use the Titebond 2 only if you plan to fly off water. Regular is much easier to use as the open time and shelf life differ between the two. Titebond will set up so calmps can be removed from a good joint in as little as 15 minutes. If you need to remove a joint water will do the trick as well as heat.
