With servos centered, position
each arm 90° to the servo case.
❏
1. Use your radio to center each of your servos. Remove
the servo arms and reposition each one so that the servo arm
is 90° to the servo case. Prepare two aileron servos and one
elevator servo as shown in the sketch. Clip off the unused
servo arms. Reinstall the servo arm screw on each servo.
❏
2. Using a #57 [1.09mm] drill bit, enlarge the hole that is
5/16" [7.9mm] from the output shaft on each servo arm. If
you don’t have a #57 drill bit, carefully use a hobby knife to
enlarge the hole until you can fi t the 1mm Z-bend pushrods.
❏
3. Route the elevator servo lead through the slot in the
bottom of the fuselage. Make sure that the servo’s output
shaft faces forward and the servo arm faces up toward the
top of the model. Clean the servo with denatured alcohol,
then glue into position as shown using thick or medium CA.
❏
4. Identify the left and right aileron servos and tie each
servo lead guide string to its corresponding servo lead. Pull
each servo lead through the fuselage and glue each servo
in position.
❏
5. Remove the guide strings from the aileron servo wires.
Attach the supplied Y-harness to the two aileron servo leads
and the 14” [365mm] extension to the elevator servo lead using
electrical tape or 3/8” [9.5mm] diameter heat shrink tubing to
secure the connections. Tie the guide string to the aileron
Y-harness and the elevator extension lead and route the wires
into the radio compartment. Note: You should be careful to
match the polarity of the servo leads with the lead extensions.
❏
6. Pull the servo leads through the upper channel so that
they are positioned as shown. Route the elevator lead so that
