-inch (67mm) is exposed forward of the firewall.
Use medium CA to glue the tube to the firewall.
Step 9
Position the throttle servo on the same side of the fuselage
as the pushrod tube and the output of the servo facing the
rear of the fuselage. Use a pencil to mark the locations for
the four servo mounting screws.
Step 10
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 11
Place 2–3 drops of thin CA in each hole to harden the
surrounding wood.
Step 12
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 13
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 14
Use four 8-32 x 1

tightening the bolts quick work.
