5)
Test fit the stopper assembly into the tank. It may
be necessary to remove some of the flashing around
the tank opening using a modeling knife. If flashing is
present, make sure none of it falls into the tank.
6)
When satisfied with the alignment of the stopper
assembly tighten the 3mm x 20mm machine screw until
the rubber stopper expands and seals the tank opening.
Do not over tighten the assembly as this could cause
the tank to split.
7)
Using a modeling knife, cut 3 lengths of fuel line
150mm long. Connect 2 lines to the 2 vent tubes and 1
line to the fuel pickup tube in the stopper.
8)
Feed three lines through the fuel tank
compartment and through the pre-drilled hole in the
firewall. Pull the lines out from behind the engine, while
guiding the fuel tank into place. Push the fuel tank as
far forward as possible, the front of the tank should just
about touch the back of the firewall.
Blow through one of the lines to ensure the fuel lines
have not become kinked inside the fuel tank compart-
ment. Air should flow through easily.
9)
To secure the fuel tank in place, apply a bead of
silicon sealer to the forward area of the tank, where it
exits the fuselage behind the engine mounting box and
to the rear of the tank at the forward bulkhead.
Do not secure the tank into place permanently until after
balancing the airplane. You may need to remove the
tank to mount the battery in the fuel tank compartment.
Pushrod wire
Install one adjustable metal connector through the third
hole out from the center of one servo arm, enlarge the
hole in the servo arm using a 2mm drill bit to accommo-
date the servo connector. Remove the excess material
from the arm.
After installing the adjustable metal connector apply
a small drop of thin C/A to the bottom nut. This will
prevent the connector from loosening
during flight.
2. INSTALLING THE THROTTLE PUSHROD
IV. COWLING
1)
Slide the fiberglass cowl over the engine and
line up the back edge of the cowl with the marks you
made on the fuselage.
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. Hold the cowl firmly in place using
pieces of masking tape.
