16. Place the spinner cone on the backplate so the
openings for the propeller in the cone are not touching the
propeller. Use a 4mm hex wrench or ball driver to install the
spinner mounting screw.
17. Attach the muffler to the engine using the hardware
included with the muffler. Connect the line from the fuel tank
vent to the muffler. Trim the line so it won’t interfere with the
operation of the engine. Use a small amount of threadlock on
the screws to prevent them from vibrating loose.
hint
: The installation of the optional EVOM1 muffler
will increase the speed of the engine over 1500 rpm on
an APC 10 x 7 propeller.
18. Place 2–3 drops of thin CA in the holes for the
throttle servo mounting screws. Remove the horn from the
throttle servo and use the hardware included with the servo
and a #1 Phillips screwdriver to mount the throttle servo in
the fuselage. Route the lead from the servo under the tray
and plug it into the throttle port of the receiver.
19. Prepare the servo horn for the throttle by enlarging
a hole that is 1/2-inch (13mm) from the center of the horn
using a pin vise and 5/64-inch (2mm) drill bit. Insert the
brass pushrod connector in the hole of the servo horn that
is 1/2-inch (13mm) from the center of the horn. Use the
connector backplate to secure the connector to the horn. Use
side cutters to remove any arm on the horn that will interfere
with the operation of the radio system.
20. Center the throttle servo using the radio system.
Slide the pushrod wire through the hole in the brass
pushrod connector and attach the servo horn to the throttle
servo so it is perpendicular to the servo center line. This
provides equal throw to both low and high throttle. Secure
the horn using the screw removed from the servo and a #1
Phillips screwdriver.
21. Move the throttle servo to the low-throttle position
using the radio system. Use the linkage to close the
carburetor then use the 3mm x 4mm machine screw to
secure the pushrod to the brass pushrod connector. Use
threadlock on all metal-to-metal fasteners to prevent them
from vibrating loose.
