Step 13
Use the screws provided with the servo and a #1 Phillips
screwdriver to secure the throttle servo in the fuselage. Make
sure to plug the throttle servo into the throttle channel of the
receiver at this time.
Step 14
Use the radio system to center the throttle servo. With the
throttle stick and trim centered, the arm should be positioned
as shown in the previous photo. This will provide an equal
amount of travel to both full and closed throttle.
Step 15
Use four 8-32 x 1

-inch socket head bolts, four #8 washers
and four 8-32 lock nuts to secure the engine. Make sure
the engine is positioned so the driver washer is 5

(138mm) forward of the firewall. A 9/64-inch hex wrench or
ball driver and a 11/32-inch nut driver or socket will make
tightening the bolts quick work.
Hint
: You can loosen the mounts on the firewall to
make it easier to install the engine. Just make sure the
mounts are tight before tightening the engine mounting
bolts.
Step 16
Remove the arms from the throttle servo that will not be
used so they don’t interfere with the operation of the servo.
Use an arm that has a hole that is 1/2-inch (13mm) from the
center of the servo horn.
Step 17
Slide the plywood pushrod support on the pushrod at this
time. Do not glue the support until instructed to do so.
Step 18
Thread a clevis on the 13
1
/
4
-inch (335mm) pushrod wire.
Make sure to slide a piece of safety tubing on the clevis.
Step 8
Use medium grit sandpaper to roughen the first 1-inch
(25mm) of the tube on each end.
Step 9
Slide the pushrod tube in the hole in the firewall. Use
medium CA to glue the tube to the firewall so it is flush with
the front of the firewall.
Step 10
Position the throttle servo on the same side of the fuselage
as the pushrod tube with the output facing to the rear of
the fuselage. Use a pencil to mark the locations for the four
servo mounting screws.
Step 11
Remove the servo and use a drill with a 1/16-inch (1.5mm)
drill bit to drill the holes necessary for the servo mounting
screws.
Step 12
Place 2–3 drops of thin CA in each hole to harden the
surrounding wood.
