The plane will look better if you glue first, cover the joints with a strip of monokote and then cover the strips with full pieces. It does take longer, as MinnFlyer says, but it sure does look better than having the exposed joints. It all comes down to how much work you want to do...it's up to you.

If you're using CA hinges, use CA. If using nylon hinges use CA and tookpicks. I have a demo on how to do the CA/toothpick method at post #45 in this thread:

In the same thread, at post #52, you can see how strips are used at the junctions in the last picture.
