Detail or aileron, ribs and spar at tip. Balsa tip will be added later.

A 1/6" sub-leading edge is glued to the front of the ribs. A 1/8" leading edge is added AFTER the top sheeting is applied.

1/16" top sheeting is added to wing structure with a built-in 1/8" washout. (See jig on plans). The balsa wing tip is glued to the tip rib and the tip is sanded to shape. Wing is now ready for joining with 1" dihedral at each tip.

The ailerons are cut from the completed wing and the leading edge of the aileron is beveled slightly to allow for 3/16" up and down movement. Shape the leading edge of the wing as shown in a typical wing section. Wrap the center section of the wing with a strip of 2.6 oz fiberglass cloth and soak with thin CA glue. The wing is now substantially complete!

The aileron servo has been installed in the wing and the wing is now ready for fitting to the fuselage. The wing will be permanently glued in place.
