❏ 9. Glue the wing tip blocks to the wing tip at

each W-13. Refer to the plans, then shape the tips

with a razor plane and a sanding block.

❏ 10. Temporarily install the wing dowels, then

glue the partially shaped wing center leading edge

to the wing.

❏ 11. Remove the dowels and use a razor plane

and a sanding block to blend the center leading

edge to the rest of the wing. After the shaping is

done, glue the dowels in the wing with 30-minute

epoxy. Be certain that the dowels are “keyed” into

the aft dowel plate – look in the wheel wells

through ribs W-2.

❏ 12. Complete the sheeting of the wing by filling

any spaces that have not been sheeted with left

over 1/16" balsa – areas such as the aft center

section of the wing where the flaps have not been

cut away from the wing and the corner of the wing

where the flap and ailerons meet.

❏ 13. Cut the hole in the top wing sheeting for the

1/4" x 2" nylon wing bolts. Hint: Push a 1/4" brass

tube sharpened at one end through the hole in the

bottom sheeting (made earlier) and through the

wing bolt plate into the top sheeting.

Use a backup

block so you don’t punch a hole through your hand!

❏ 14. Insert the wing bolt into the holes you made.

The heads of the bolts will stop at the sheeting

because you have not enlarged the holes yet.

❏ 15. Place the cardboard wing tube over the

heads of the bolts and trace around them with a

pen. Remove the tube and the bolts then make the

holes for the wing bolt tubes. Slightly enlarge the

1/4" holes in the top of the wing sheeting to allow

the wing bolts to pass easily.

Oh boy! We can get a good idea of how big this

thing is going to be and how cool it’s going to look

by mounting the wing to the fuse and setting it on

its landing gear for the first time! This will only take

a few minutes...

MOUNT THE WING TO THE FUSE

❏ 1. Trim the fuselage sheeting until it accurately

matches the contour of the balsa wing saddles.

Sand only to the balsa saddles and do not change

the shape of the plywood crutches as this

determines the wing incidence.

❏ 2. Set the wing in the fuselage with the dowels in

the dowel holes in former F-2. Make slight

adjustments to the dowel holes in F-2 if required.

❏ 3. Align the wing with the fuselage by holding a

string with one end attached to a pin centered at

the tail, up to a wing tip. 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.

Adjust the position of the wing until it is properly

aligned.

NOTE: Make sure the wing is held

securely and cannot shift while you are drilling

the mounting holes.

❏ 4. With the wing aligned and held in place (tape or

tack glued), insert a 1/4” drill and lightly mark the

center of the wing mount holes on the mount blocks.
