Yeah, it was a bit strange. The rib was starting coming apart on the outside, not where I glued the wing halves together.

The flap movement seems to be restricted by the flap linkages. I suppose I could bend them to get more movement, but some people at the field advised me to redo the flaps. I used Dubro pinned hinges instead of the CA hinges, and all of them hold up just fine so far.
