Step 10
Slide the wire through the hole one in from the end of the
elevator servo arm. Secure the wire using a nylon wire keeper.
Step 11
Repeat Steps 1 through 10 for the rudder linkage.
Step 12
Slide a clevis retainer onto a nylon clevis. Thread a clevis onto a
4 3/8-inch wire a minimum of 10 turns.
Step 13
Remove the backplate from a control horn using side cutters or
a sharp hobby knife.
Step 14
Position the control horn on the aileron so the horn aligns with
the hinge line of the aileron. Mark the position for the mounting
holes using a felt-tipped pen.
Step 15
Drill three 3/32-inch holes at the locations marked in the
previous step.
Step 16
Place 2–3 drops of thin CA into the hole to harden the wood.
Repeat this for each of the three holes.
Step 17
Attach the control horn using three 1.5mm x 15mm screws and
the control backplate.
Step 18
Center the aileron servo electronically using the radio system.
Install a servo arm onto the aileron servo. Attach the pushrod
with clevis to the control horn. Physically place the aileron
control surface in neutral. Mark the pushrod where it crosses
the holes in the servo arm.
Step 19
Bend the wire 90-degrees at the mark made in the previous
step. Cut the wire 3/8-inch (10mm) above the bend.
Step 20
Slide the wire through the outer hole in the aileron servo arm.
Secure the wire using a nylon wire keeper.
Step 21
Repeat Steps 12 through 20 for the other aileron servo.
Step 22
Center the throttle stick and trim with both the receiver
and transmitter on. Install the throttle servo arm in the
neutral position.
Step 23
Move the servo to the throttle closed position using the radio
system. Manually move the throttle arm to the closed position.
Mark the location where the pushrod crosses the servo arm
using a felt-tipped pen.
