If you were able to work fast enough to get it together straight--and it's not twisted--then leave it be.

The dihedral braces are doing all the work. All the epoxy does is fill in the voids. I've glued the horizontal stab on a small 40 size ARF with 5 min before. Had to work fast, but it held up for about 300 flights before a deadstick led to me stuffing the airplane. The stab was still glued solidly in place. All that joint is--is a flat piece of balsa glued onto 2 pieces of 1/4" balsa and it's constantly trying to seperate itself when you push and pull the elevator stick.

With a wing joint--you have a dihedral brace. The brace fits in the pocket. Thats what it keeping your wings from folding in a high G turn. Not the epoxy. All the epoxy does is keep it from wiggling inside the pocket and keeps the the wings from sliding outwards and away from the dihedral brace.

Leave it be and go fly it. You'll be fine.
