I never liked the use of fiberboard on Centuri models but that was what the kit came with. This time I used 1/16 inch balsa covered with label paper. Because of the complex shape of the fins I decided to divide the bigger fin patterns so the leading edge would go along the direction of the wood fiber. Covered them with label paper then placed them on a flat surface then placed a glass cutting board with weights over it for 24 hours to ensure the paper would stick well to the balsa. Then sealed the edges with one coat of crazy glue, sanded the edges, then applied a 2nd coat of crazy glue, waited for the glue to cure, then a final light sand along the edges.

The fins came out very nice, light, and strong. Used Gorilla wood glue to attach the fins and ran one coat of glue along the roots as fillets. Thinking now of running a thin layer of epoxy as a 2nd coat of fillet.
