❏
1. Mount the throttle servo as shown on the plan using the
hardware that came with your servo. Once the servo is
mounted, remove the screws and servo. Add a few drops of
CA to each hole to harden the threads. Allow the CA to fully
harden, and then reinstall the servo.
❏
2. Install a screw-lock connector on the throttle servo
arm on the furthest-out hole.
❏
3. Install a nylon clevis and retainer to the 42" [1070mm]
throttle pushrod wire. Slide the pushrod through the pushrod
tube with the clevis on the carb end.
❏
4. Bend the carb end of the throttle pushrod as needed to
fit the engine installation. Make adjustments to the bends in
the wire so the pushrod aligns with the carburetor arm on
the engine, and then temporarily connect the pushrod to the
carb arm. Temporarily mount the muffler and make sure the
throttle pushrod will not interfere with the muffler. Make
adjustments to the bends in the wire if necessary.
❏
5. Slide the pushrod wire through the screw-lock connector
on the throttle servo and temporarily tighten the screw.
❏
6. Insert the two elevator servos, the rudder servo, and the
retract servo (if used) as shown. Align the servos with the
pushrods and mount the servos using the screws provided
by the servo manufacturer. Once the servo is mounted,
remove the servo and harden the threads with thin CA.
❏
7. If installing fixed gear, route the remaining 42"
[1070mm] pushrod through the firewall and guide tube until
it reaches the servo. Install a screw lock connector on the
rudder servo arm for the nose wheel. If you installed
retracts, see the photo above for reference. With a nose
gear retract, the pushrod and pushrod tube will not exit the
firewall. You will need to cut the pushrod and tube to the
approximate length shown. Using a leftover balsa stick, make
a support for the pushrod tube inside the tank area. Attach
the clevis to the steering arm on the retract.
