4. Make a mark on the fi rewall that is aligned with the
throttle arm and the throttle servo. On the mark drill a 3/16"
[4.8mm] hole. Locate the 12" [305mm] plastic tube. Cut it
to a length of 7-3/4" [197mm] and roughen the end of the
tube with 180 grit sandpaper. Slide the tube into the hole
so the roughened end of the tube makes contact with the
fi rewall. Adjust the tube so it is aligned with the throttle
servo. Apply glue to the roughened end of the tube gluing
the tube to the fi rewall.

5. Install Velcro through the forward slots as shown.
❏
6. Mount your throttle servo to the throttle servo tray
with the hardware that came with the servo. Install a short
servo horn and then install a brass screw lock connector in
the outer hole of the arm. Secure it to the arm with a nylon
retainer. Install a 4-40 x 1/4" [6.4mm] socket head cap screw
into the connector.

7. Assemble the fuel stopper as shown. The fuel system
shown here is a three line system having a vent line, carb
line, and fi ll line. The rubber stopper has two open holes for
the aluminum tubing and one additional hole that you will
need to puncture above the sealed off fuel tube hole. The fi ll
and carb lines should extend out 1/2" [12.7mm] beyond the
stopper and the vent line should be bent upwards and left
uncut. With the tubes installed in the stopper, fi t the stopper
plates loosely in place with the 3x25mm phillips screw to
hold the assembly together.

8. Fit the stopper assembly into the tank with the vent
line pointing toward the top of the tank, but not touching.
The fuel tubing and clunks (fuel pickup) on the carb and fi ll
lines should almost reach the back of the tank but not touch.
The clunks must be able to move freely inside the tank when
assembled. Adjust the length of the fuel tubing accordingly.
When satisfi ed, tighten the 3x25mm screw in the stopper to
secure it in place (do not over-tighten). Mark the side of the
tank that must face up when installed in the plane. We also
suggest marking the tubes in the stopper.
❏
9. Attach fuel tubing onto each line coming from the tank.
Insert the tank into the fuselage with the correct side facing
up. The fuel tubing should be routed through the hole in the
center of the fi rewall. Secure the tank with the Velcro you
installed earlier.
