5. Reconnect the pushrod to the servo horn, then mark

and drill 1/8" [3.2mm] holes through the aileron for the
control horn mounting screws. Mount the horn to the aileron
with four 4-40 x 3/4" [19mm] screws and the mounting plate
on the top.

6. Make the other aileron pushrod the same length as the

first, then hook up the other aileron with another control
horn and mounting screws.

7. If you’re building your model

without flaps, make two

more pushrods the same way and connect the “flap” servos
to the “inner ailerons.” Then proceed to

“Finish the Wings.”

If you

are building flaps, follow steps 8 through 10.

Now onto the flaps…

8. Place a servo arm on one of the flap servos. Rotate

the arm downward 30-degrees.

9. Make the flap pushrod and connect the flap to the flap

servo the same way you did the ailerons.

10. Hook up the other flap the same way.

1. Round one end of the 1/4" x 1-3/16" [6.4 x 30mm]

hardwood anti-rotation dowel. Use 30-minute epoxy to glue
the dowel into the end of one of the wings. Glue both 3/8" x
2" [9.5 x 50mm] hardwood wing dowels into the front of both
wings. 3/8" [10mm] of the wing dowels should protrude.

2. Cut the covering from the wing bolt holes in the wings and

from the holes in both 1/16" [1.6mm] plywood wing bolt
plates
. Place the wing bolt plates on the wings using the
1/4-20 x 2" [50mm] nylon wing bolts to hold them in place. Mark
the outline of the wing bolt plates onto the wings using a
ballpoint pen. Remove the wing bolt plates and cut the covering
from the wings 1/8" [3mm] inside the lines you marked.

3. Glue the wing bolt plates into position using the wing

bolts to keep them in alignment.
