Next was to do the servo boxes in the wings. I hate these so they are as simple as I can make them LOL

All 1/8" balsa, with 1/8" ply rails and 1/4" sq balsa underneath for support. Because the model is electric I am not as concerned about the rails being sunk into the sides of the boxes. If the model were glow I would make these more solid.

Since I am doing 4 wings at once, I made all the pieces in one shot, basically with a table disc/belt sander. I bench assemble the boxes with CA, then make sure they fit the pre-cut holes in the wings, and basically put poly-u glue on them and drop them in place, then finish sand to the surface afterwards.
