If you want to speed your building time get some kicker. This will set the CA almost instantly. For gap filling also get some wood fibres or micro ballons. [ Everybody has the odd gap! ]

However if you have really tight joints just thin CA seems to work fine for me. I built a 90 size wing that had been laser die cut with nice tight joints entirely in my hand, eyeballed it for square then ran thin CA into all the joints. As far as I know that model is still flying after 5+ years and some serious air time.
