No offense guys..........BUT, he asked for help with a problem and all he gets is negative crap about what he has done. Did that help him at all?

1) It sound like you might have used to much glue.It should be OK with time. You could also scrape a little of it off with a razor.
On your next plane let gravity help you. Like on the wing stand it up on it's leading edge when you drip toward the wing. Then
flip it over when you drip toward the AILE.

2) Once again you might have used to much glue. I assume you are using thin not med CA.

3) This is normal they should break in. I learned on RCU to use a Crayon to mark both sides of the hinge line before instalation.
The Crayon wax will keep the CA from soaking the center area.

Please excuse my ignorence of Italy. Do you know what a Crayon is?
