macross, leg connector r damn tight & fragile, easi to broke. i broke mine.   
decal scar when transform.
highly recomend to get dx version.

why do i sound like trolling? 1/144 is so small you use so little paint when using airbrush it's not worth the time to clean it and change paint, unless you have multiple airbrush line up then it's easier can clean when finish. but if you use can spray paint it's so much more convenient.

to me painting is the hard part, assembly is much easier, of course exclude PG. so i really want to use airbrush i would prefer building at least MG. but seasoned builder like you probably can paint x3 faster than me.
