MOUNT THE WING ❏ 1. Round one end of both 1/4" x 2-1/4" [6.4 x 57mm]
hardwood wing dowels. Use 30-minute epoxy to glue
the dowels into the wing. Allow the epoxy to harden before fitting the wing to the fuselage.
❏ 2. Using the wing bolt holes that are already in the
top of the wing as a guide, use a 3/16" [4.8mm] brass tube sharpened on the end or a 3/16" [4.8mm] drill bit to the holes through the bottom sheeting.
❏ 3. If you haven’t done so already, use a bar sander
with 80-grit or 150-grit sandpaper to sand the balsa fuselage sheeting even with the plywood fuselage doublers and former F3 to accommodate the wing. Test fit the wing in the fuselage and make any adjustments necessary for a nice fit.
❏ 4. With the wing in the fuselage, stand six to ten
feet behind the model. View the alignment between the wing and the stabilizer. If the two are in alignment proceed to the next step. If the wing and stab do not align, remove the wing and carefully sand the “high side” of the wing saddle in the fuselage to bring the wing into alignment with the stabilizer.
❏ 5. Stick a T-pin into the bottom of the fuselage
centered over the bottom stringer at the rear. Tie a loop in one end of a 60" [1.5m] piece of non-elastic line such as monofilament or Kevlar line. K & S #801 Kevlar thread works perfectly for this. Slip the loop in the string over the T-pin.
❏ 6. Fold a piece of masking tape over the string
near the other end and draw an arrow on it. Slide the tape along the string and align the arrow with one end of the wing as shown in the photo. Swing the string over to the other end of the wing and hold it in the same position. Rotate the wing as necessary and slide the tape along the string until both ends are equalized. Now the wing is centered.
❏ 7. Being careful not to disturb the wing alignment,
drill #7 holes through the wing and the wing bolt blocks in the fuselage.
