2. Mark 1/4” from the end of the .063 wire and
make a 90º bend.
3. Cut the wire to a length of 12-3/8”.
4. Cut off a piece of nylon guide tube 9-1/2”
long.
5. With the engine in place on the motor mount,
mark the location for the throttle pushrod on
the firewall.
6. Remove the engine and drill a 1/8” hole for
the pushrod in the firewall.
7. Next, drill two 1/4” holes for the fuel tubing.
Take the 20” length of fuel tubing and pass
equal amounts of the tube into each of the
holes, so that equal lengths of tubing are
inside the fuselage.
8. Insert the 9-1/2” guide tube through the front
of the firewall back to the throttle servo.
Make sure the tube goes through the hole in
the former, as shown above.
NOTE: A short length of guide tubing should extend
out the front of the firewall.
9. Holding the engine in your hand, take the
bent end of the .063 wire and place it on the
throttle arm of the engine. Then, slide the
other end of the wire into the guide tube.
Make sure the throttle wire goes through the
tubing in the fuselage and over the top of the
throttle servo.
10. Place the throttle wire through the hole in the
pushrod connector and slide the servo arm
on the wire to the top of the servo, as shown.
NOTE: It may be necessary to bend the wire to pre-
vent any binding.
11. Twist the servo until the arm is pointing
towards the engine and then push the wire
forward until it stops moving.
Tighten the setscrew on top of the pushrod
connector. Final adjustment can be made
later, when the rest of the radio is installed.
