servo and wick a few drops of thin CA into each of the four
holes. Mount the servo to the wing with the screws included
with your servos.
❏ ❏
3. Mount your other aileron servo in the opposite wing
panel using the same procedures as above.
❏ ❏
4. Cut the unused arms from one of your servo horns
and mount it on one of your aileron servos in the wing. The
remaining arm faces the tip of the wing.
❏ ❏
5. Hold the
control horn
on the aileron, making sure
the holes align with the hinge gap. The horn must also rest
on the plywood plate installed in the aileron. Use the control
horn as a template to drill 3/32" [2.5mm] holes in the aileron
for the mounting screws.
❏ ❏
6. Screw the
#4 x 5/8" self-tapping screws
into the
holes. Remove the screws, and apply three drops of thin CA
to each hole drilled to harden the underlying plywood. Re-attach
the control horns using the #4 x 5/8" self-tapping screws.
❏ ❏
7. Thread a
4-40 hex nut
and a
4-40 threaded clevis
onto the threaded end of the pushrod wire. Attach the clevis
to the control horn.
❏ ❏
8. Use a felt-tip pen to mark the pushrod wire where
it crosses the holes in the aileron servo arm. Cut the
pushrod wire 3/4" [19mm] behind the mark.
❏ ❏
9. Locate a
solder clevis.
Use the following sequence
to solder the clevis to the pushrod:
❏ ❏
A. Lightly sand the pushrod and clean it with alcohol.
❏ ❏
B. Insert the pushrod into the non-threaded clevis.
The wire should protrude 1/16" [1.5mm] inside the forks of
the clevis.
❏ ❏
C. Apply a small amount of soldering flux to the joint.
❏ ❏
D. Apply heat evenly to the pushrod and the clevis and
then touch the solder to the joint and allow it to flow.
❏ ❏
E. Allow the pushrod and clevis to cool slowly before
continuing.
❏ ❏
10. Place a
clevis retainer
onto both of the clevises.
Attach the pushrod to the servo and control horn.
❏
11. Return to step 4 and connect the other aileron servo
to the other aileron the same way.
❏
12. Turn the wing over. Use the string out of the 1/2"
[13mm] holes in the center-section of the wing to retrieve
your aileron servo cords.
Note:
The procedure for installing the elevators to the
stabilizer is similar to the installation of the ailerons.
❏
1. Cut six 3/4" x 1" [19mm x 25mm] hinges from the CA
hinge strip supplied with this kit. Snip the corners off so they
go into the slots easier. You may cut all the hinges now, or
cut them as you need them.
❏
2. Test fit the elevators to the stabilizer. If the hinges are
difficult to install or don’t go in far enough, carefully enlarge
the hinge slots with a hobby knife and a #11 blade.
❏
3. Drill a 3/32" [2.5mm] hole, 1/2" [13mm] deep, in the
center of the hinge slot. If you use a Dremel MultiPro for this
