That aileron cut job is really clean!! Well played
30 min Epoxy, and foam safe medium CA, are the bare minimums
Micro balloons are a smart thing to have....they are added to epoxy for thickening and weight saving when there are gaps to be filled/bridged....like your wing joint.
I also like shoe goo or some thing like it for gluing the servo tray and servos in, but you can use epoxy too, it's just harder to take back apart if something breaks.
