MOUNT THE WING TO THE FUSELAGE
❑ 1. Run a 5/16” drill through Formers F-2 and
F-2C to clean out the holes so the dowel will fit
through.
❑ 2. Round the ends of the 5/16” Diameter x 3-
1/8” hardwood Wing Dowel.
❑ 3. Tape some scrap 1/32” plywood (from the
wing fillet base die-cut sheet) to the wing skin
where it will intersect the fuselage to simulate the
die-cut 1/32” plywood Fillet Base. Test fit the wing
to the fuselage. If there is much interference
preventing the wing from comfortably fitting down
on the saddle, shape the wing dowel hole in F-2
oblong and adjust the dowel slot in the wing
structure until the interference is gone.
❑ 4. Put the wing in position on the fuselage.
Hold a string (with one end attached to a pin at the
tail) up to one of the wing tips. Put a piece of tape
on the string to mark the intersection of the string
and the wing tip. Swing the string over to the other
wing tip and check to see if the distances are the
same (see diagram). Adjust the position of the
trailing edge of the wing until the wing is properly
aligned.
NOTE: Make sure the wing is held
securely and cannot shift while you are
drilling the mounting holes.
❑ 5. With the wing aligned and taped in place,
mark the center of the wing mount holes on the
mount blocks with a #10 (or 13/64”) drill.
❑ 6. Remove the wing to prevent damage to the
wing and mounting holes. Finish drilling the holes
