2.INSTALLING THE FUSELAGE SERVOS
1 1) Install the rubber grommets and brass collets
into the elevator, rudder and throttle servos. Test t
the servos into the servo tray. Trim the tray if neces-
sary to t your servos.
1 2) Mount the servo to the tray using the mounting
screws provided with your radio system.
1 5) Test t the stopper assembly into the tank. It may
be necessary to remove some of the ashing around
the tank opening using a modeling knife. If ashing is
present, make sure none of it falls into the tank.
1 6) When satis ed 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.
1 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.
1 8) Feed three lines through the fuel tank compart-
ment and through the pre-drilled hole in the rewall. 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 rewall.
Blow through one of the lines to ensure the fuel

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 ight.
3. INSTALLING THE THROTTLE PUSHROD
from the rear of the tank and move freely inside the
tank). Connect one end of the line to the weighted
clunk and the other end to the nylon pick up tube in
the stopper.
1 3) Carefully bend the second nylon tube up at a 45
degree angle (using a cigarette lighter). This tube will
be the vent tube to the muf er.
1 4) Carefully bend the third nylon tube down at a 45
degree angle (using a cigarette lighter). This tube will
be vent tube to the fueling valve.
When the stopper assembly is installed in the tank, the
top of the vent tube should rest just below the top sur-
face of the tank. It should not touch the top of the tank.
lines have not become kinked inside the fuel tank
compartment. Air should ow through easily.
1 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.
