I find that normal (white) wood glue is about as strong as you'll need in building model aircraft. I've used white glue for years in numerous applications, and found it really satisfactory. My observation is that a wood joined with white glue, if prised apart with a chisel, will split the wood, whereas a joint with epoxy will usually pull the glue itself apart, and that tells me that the white glue makes a stronger joint.

There is another glue that I think is better than all others, and that's Fuller's Max Bond. It's thick and difficult to use on small applications though, more a construction industry glue, but for bulkheads to fuselage, it can be used successfully. Liquid Nails is similar.

The advantage I find with white glue in modeling is that when it comes time to repair, and there will be such a time, the cleanup and repair will be easier than if epoxy was used. It can be cleaned off and sanded easily, and a new joint made much more easily than the epoxy joint.

However if there is even a slight possibility of a gap, then white glue is not suitable. It doesn't gap fill.
