Status: offline 		I am scratch building a 90 size fun fly plane using wing tubes. My inner two ribs are lite ply and I will have 2 each 1/4"dowels pinned into the fuselage and a hold down bolt. This is my question. Right now my design has a 5/8” dowel that glues to these two ply ribs that is tapped for a 1/4-20 bolt. Is this OK for a nylon bolt or should it be aluminum? See attached picture.

As long as there's long tubes in the wings that plug into the center section tubes, you should be OK.
