Is it just the fuse that's out of kilter now?

If the stab/elevator was glued to it, and that fuse is now curving around, how parallel to the wing do you think the stab/elevator is now?

Depending on how bananna like the fuse is now, both the fin/rudder AND the stab/elevator are going to be working off line when they work.

How bad will it be? None of us have a snowball's chance of knowing.

If you haven't covered the fuse yet, fix it before covering. If you have, then go fly it and see. The beauty of our hobby is that it is so very easy to test things for ourselves. But if you're really worried about the bananna being hard to handle, take a picture and let us actually see how bad it looks. We'll be glad to give all manner of sage advice. And then you can have the ultimate fun this hobby offers. You can then go test and find out who guessed right and who didn't. There are lots of different ways this hobby can give us a chuckle.
