I used to build em when I was in highschool. Hmm... I should get back into it...
If he's always wanted to build that plane, then he's gonna want it looking good. You'll probably have to get a high skill level kit with at least a couple hundred peices for realism. THat, and he'll need a paint set so that he can paint the parts BEFORE putting them together for the highest level of accuracy.
Of course, that'll require some experience to do correctly, so you might wnana get him a lower level kit or maybe just a high quality prebuilt model of the airplane.
