(Note: Regardless of your engine’s or radio’s manufacturer, it is wise to maximize the distance
between your engine’s and your radio’s electrical components.)
26.
Trial fit both switches (trim the openings if necessary) and install the engine and receiver switches.
27.
Test-fit the engine’s
ignition module
immediately behind the firewall. Decide how
you plan to route the power, sensor and spark-plug wires. (Note: If you find the
ignition module’s spark plug cap does not easily pass through the hole in the fire-
wall, you may relieve the inside top of the hole in the firewall with a drum sander
on a high-speed rotary tool; the ignition module may not include mounting flanges.)
28.
Test fit your engine and muffler to the firewall. Use the engine’s supplied
standoffs, mounting bolts and blind-nuts to temporarily attach the engine to the
firewall, then determine and mark where
wood may need to be cut away from the
front of the fuselage to allow clearance for the engine’s cooling fins and muffler.
29.
Remove and set aside the engine.
30.
Remove any excess wood identified above
and smooth all edges. Apply 5-minute epoxy
to
seal and fuel-proof
all exposed/raw wood.
31.
Once the epoxy is cured,
install your engine,
its muffler, and make all engine connections:
As you bring the engine toward the firewall,
your first connection should be the throttle
pushrod’s Z-bend; then, secure the four sets
of mounting bolts and standoffs and apply
Lock-Tite or a similar thread-locking
compound. (NOTE: EZ Link connectors may
be used, but are not included.)
32.
Route the high-voltage wire along the
engine’s left side, between the cylinder head
and muffler; route the sensor wire and the
fuel and vent lines along the engine’s right-
hand side.
33.
Place the throttle servo’s control arm onto
your throttle servo’s output shaft, attach the
servo arm’s mounting screw, rotate the
servo’s shaft to ‘full throttle’ and position the
throttle servo so the engine’s throttle linkage
is at ‘full throttle.’ (NOTE: If necessary,
make a new hole in the firewall for the
pushrod to align with the location of the
carburetor’s throttle arm. We recommend you
do not void your engine’s warranty by
disassembling or modifying the engine.)
34.
Cut away the Mylar covering material
from the wing’s hold-down bolt holes and from the correspond-
ing holes in the plywood wing hold-down plate.
35.
Connect
the rudder and elevator extensions, the throttle servo, and the receiver’s battery switch to
your
receiver
. If you are not setting up your radio for electronically-managed differential aileron response,
connect a Y-cable to your receiver’s aileron channel. If you have a computer-radio and will be setting up
