7. Sand the stab and fin tips to match the taper of the

elevators and rudder.

1. Shape the leading edge of the elevators and rudders to

a “V” as shown on the plans.

2. Use a bar sander and 150-grit sandpaper to round the

tail surfaces as shown on the plan.

Note: Wing construction is engineered to provide a straight-
and-true wing panel with minimum effort. To do so, the
building sequence and pieces are different from what you
may be accustomed to. Be sure to read all steps carefully
and pay particular attention to instructions of when and
where to apply adhesives.

Note: The wings are built upright over the plan. You may
build both wing panels at once following the instructions if
you have space to do so.

❏ ❏

1. Lay the right wing panel plan on a flat building

board and cover with wax paper or plan protector.

❏ ❏

2. Cut the bottom main wing spar to the length

shown on the plan from a 1/8" x 1/2" x 36" [3 x 13 x 910mm]
basswood stick. Pin the spar to the plan.

❏ ❏

3. Cut the bottom aft wing spar from the leftover

1/8" x 1/2" [3 x 13mm] basswood stick.

❏ ❏

4. Lay out the die-cut 3/32" [2.4mm] balsa wing ribs

R2 through R10 in the general area of their location on the
plan. Rib R4 will be installed in the last step and can be set
aside for now.

❏ ❏

5. Place the die-

cut 1/8" [3mm] balsa
main wing web on
the spar along the
leading edge.

❏ ❏

6. Use the 1/2" [13mm] holes to align the die-cut 1/8"

[3mm] plywood rib doublers R3A with ribs R3. Glue in place
with medium CA. Make a right and a left. Note: There is a
slight offset in the slots on the ribs as compared to the
doubler. This is normal.
