MOUNTING THE ENGINE.
! 1) Install the pushrod housing through the
predrilled hole in the firewall and into the servo
compartment. The pushrod housing should
protrude 1/4" out past the front of the firewall.
Make a Z-Bend 1/4" from one end of the plain
wire pushrod.
! 2) Place your engine onto the engine
mount. Adjust the engine is centered of the
edges of the engine case.
! 4) Remove the engine. Using an drill bit,
drill the mounting holes through the engine
mount at the four locations marked.
! 3) When you are satisfied with the align-
ment, mark the locations of the engine
mounting.
4x30mm.
! 6) Attach the Z-Bend in the pushrod wire to
the throttle arm on the carburetor. You will need
to remove the throttle arm from the car- buretor
to be able to attach the Z-bend. When
complete, re-attach the throttle arm to the car-
buretor.
! 5) Bolt the engine to the engine mount using
the four machine screws. Double check that
all the screws are tight before proceeding.
COWLING.
! 1) Slide the fiberglass cowl over the en-
gine and line up the back edge of the cowl with
the marks you made on the fuselage then trim
and cut.
! 2) While keeping the back edge of the
cowl flush with the marks, align the front of
the cowl with the crankshaft of the engine. The
front of the cowl should be positioned so the
crankshaft is in nearly the middle of the cowl
opening. Use the spinner backplate as a guide.
Hold the cowl firmly in place using pieces of
masking tape.
Because of the size of the cowl, it may be
necessary to use a needle valve extension for
the high speed needle valve. Make this out of
sufficient length 1.5mm wire and install it into
the end of the needle valve. Secure the wire
in place by tightening the set screw in the side
of the needle valve.
