Rebelion, are you familliar with the practice of double gluing, or "sizing"?
On end grain joints, like the uprights in a fuselage, it helps to put a little glue on the end grain, wipe it off and let it set a little bit, then go back, apply glue, and put the part in place. I usually let it set long enough to make the next one or two pieces.
The first application penetrated and seals the end grain and you end up with a much stronger joint.
