I just got a monokote arf superstar 40 for my girl friend to teach her to fly and i have a build question.

Last night i was joining the wing halves and gluing the angled wood connector into the wings and had a problem. as i glued one half in and then tried to glue the other, the wings would not fit together and there ended up being a 1/2 inch gap between the 2 wings. I should have test fit it but, in my hurry to build, i did not and the joiner was too long. Of course by this time, the glue had set and i could not pull it back apart and modify. So, i just reached in and cut the joiner.

So, i now have a superstar 40 wing that has no way of joining. The "stock" joiner is now firmly glued into the joiner holes on both wings and i know that if i just epoxy the wing faces together, it will come apart on the first flight.

Is there a easy solution to this? or am i going to have to re engineer a wing joiner?
