The wing is pretty typical built-up "D-tube" construction. All 1/16 balsa. 1/4 inch square spars and 1/16 shear webs. Note: sheet the top center section, but not the bottom. All the R/C gear is going into the center section of the wing. I did use 1/8 balsa for the last ribs (wing tips). I drilled out lightening holes in every rib but the tip ribs. The airfoil is thick - this typically gives good slow-speed performance and a smooth transition from flying to hovering. To make the ribs, cut them all our roughly, pin together, then belt sand to final shape.
