One trick I picked up here on RCU was after either the replacement was made and fitted, or the parts were re-assembled and CAed together, then use a slotmachine and cut some CA hinge slots bridging the repair joint and insert a CA hinge and soak it down with Thin CA, It makes a nice reinforcement with little added weight.

It's easier to cut the hinge slot if the joint is just tacked together though. Then after the hinge is in place, soak it down. It is also easier if you cut the hinge so there is no overhang prior to the CA application. I tried this method on a broken wing and it worked very well, until the battery opened up and the bush ate the plane.
