Refer to this photo to make the aileron torque rods.
Make the left one first.
❏
6. Cut 1" [25mm] from one end of the .030" x 20-1/2" [.76
x 520mm] wire and clamp it in a vice. Cut another 5"
[130mm] from the wire and make a loop near one end by
pulling it around the wire clamped in the vice.
❏
7. Cut the excess wire from the loop. Make the first 90-
degree outward bend 1/2" [13mm] below the loop. Slide the
1-1/8" [29mm] aluminum torque rod tube onto the wire.
❏
8. Make the final bend in the wire, then cut the wire to
length shown on the plan.
❏
9. Cut another 5" [130mm] from the wire and make the
right aileron torque rod
the same way. Note that the right
torque rod is a little longer than the left.
❏
10. Make two
torque rod supports
from leftover 1/16"
[1.6mm] balsa. When resting on the supports, the torque
rods should align with the bottom surface of the trailing edge
sheeting. Glue the supports into position, then glue the
torque rod bearing tubes to the supports.
❏
11. Sheet the remainder of the top of the center section.
Fill any gaps with balsa filler and sand when dry.
Refer to this photo for the following three steps.
❏
12. Cut holes in the top sheeting for the aileron servo and
the servo wire. Glue pieces of leftover 1/8" x 1/4" [3.2 x
6.4mm] balsa to the inside of the top sheeting for the aileron
servo mounting screws. Drill 1/16" [1.6mm] holes for the
screws and add a few drops of thin CA to the holes. Allow
the CA to fully dry, then mount the servo in the wing.
