I've had this happen many times. It wasnt until years later reading
about super glue and how its really has problems with surfaces that
take stress from different directions. The lightbulb went on I was
sanding the ridges where the glue had been and squeezing them by
holding the fuslage, this would cause the joint to crack. On Resin
models I now use epoxy on those types of joins as well as superglue. 

On vacforms I do the same thing for wing joins etc. Its far stronger.

imho the best vacforms are by Dynavector... Of course I've never
built  any of there models I mean they would be the wrong scale and
era's....... ;)
