2. Test fit ribs

W2 through W14

to the die-cut

1/8” [3.2mm] balsa

spar web (W15)

. If necessary,

deepen the notches (in the ribs or in the spar web)
so the ribs fit all the way into the spar web.

Note:

Do not be concerned if the ribs do not exactly

align spanwise with the plan. Paper plans can
expand and contract as much as 1/8” [3.2mm] due to
moisture.

❏ ❏

3. Fit the ribs and spar web to the bottom spar

so the ribs align as close as possible with the plan.

❏ ❏

4. Test fit the die-cut 1/8” [3.2mm] balsa

aft

inner spar (W18)

into the notches of ribs W2

through W9. If the spar fits too tightly use a single
edge razor blade or a flat Perma-Grit sander to bevel
the notches in the ribs and the spar at the same
angle that they cross. Reinstall the aft inner spar.

❏ ❏

5. Test fit the die-cut 1/8” [3.2mm] balsa

aft outer

spar (W16)

and the die-cut 1/8” [3.2mm] balsa

aileron

spar (W17)

into the notches of ribs W9 through W14. If

necessary, bevel the notches in the spars and ribs the
same way you did in the previous step.

❏ ❏

6. Temporarily remove rib W2 from the assembly.

❏ ❏

7. One at a time, accurately align the jig tabs of

all the ribs with the plan and pin them to your building
board. In addition to T-pins, place weights on top of
the ribs and the aft spars to insure that

all the jig

tabs are contacting your building board

. Inspect

all joints and make sure everything aligns with the
plan. The spar web must fully contact the bottom
spar. A die-cut 1/8” [3.2mm] plywood

90 degree

gauge

is supplied in the kit to help you keep the ribs

vertical as you glue them.

❏ ❏

8. Use medium or thin CA to glue all the joints.

Use the CA sparingly at this stage of construction
and do not build up fillets. This will allow you to
realign parts if necessary and keep you from gluing
the jig tabs to the ribs. We will remind you to reinforce
all glue joints later.

❏ ❏

9. Place rib W2 back onto the assembly. Align

W2 with the dashed line depicting where it contacts
the plan. Use the die-cut 1/8” [32.mm] plywood

dihedral gauge

to set W2 at the correct angle. Glue

it to the bottom spar and the spar web. Glue W2 to
the aft inner spar using the dihedral gauge to set it at
the correct angle.

❏ ❏

10. Test fit a 1/4” x 3/8” x 36” [6.4 x 9.5 x

914mm] basswood

upper spar

in the notches of the

ribs so the end of the spar aligns with rib W2. Glue
the spar to the ribs and the spar web with thick or
medium CA. Remember, don’t use too much glue.
