Well, it's not a snap-tight kit so he is going to need some glue. If he doesn't have any I would recommend three as top-tier, but you can make due with one if careful.

Testors Tube Glue is the "old favorite" most people are familiar with.

Tamiya extra fine cement is great for details and long seams (fuselage and wings) but it works differently than the tube cement and some people get confused by this and think it sucks because they don't "do it right." Essentially put the parts together and then paint it along the seam as opposed to painting the joints and then putting pieces together - it's so thin that a lot will evaporate before you get the pieces joined if you apply it first.

Tamiya Clear Parts Cement is nice for clear parts like the canopy or side windows on the Lanc. You can make due with the tube glue as well but you have to be a bit more careful because it's easy to mess up any clear parts.
