175. Use 5-minute epoxy to apply hook and loop tape to the
battery and battery tray. Place two hook and loop straps
through the openings in the battery tray.
 Apply a small amount of 5-minute epoxy to the straps
to secure them to the battery tray. This will prevent them
from falling through the holes when the battery is removed.
176. Install the battery tray in the fuselage using the screws
removed previously.
 FUEL TANK INSTALLATION
177. Cut a piece of fuel tubing that will result in the end of the
clunk being 4 1 / -inches (115mm) from the back of the
2
aluminum plate. Secure the tubing to the included clunk and
stopper using thin wire. This will keep the tubing from sliding
loose inside the tank. Make sure to use the clunk supplied
with your engine. The second line will use the clunk included
with the engine.
 Apply a very small amount of soapy water to the stopper
to make it easier to install the stopper into the tank.
178. Install the stopper fully into the tank. Make sure the clunk(s)
can move freely inside the tank. If not, adjust the tubing as
necessary so they can move without binding inside the tank.
Once the clunk(s) have been positioned, tighten the screw
using a #1 Phillips screwdriver to secure the stopper in the
tank.
179. Secure a 5-inch (127mm) fuel line to the fi ll line of the tank.
The overfl ow line can be attached to the vent, as well as the
remaining tubing to the clunk line that will eventually attach
to the carburetor. Tie wraps can also be used to secure the
fuel lines as well as wire ties.

180. Secure the fuel tank in the fuselage using the hook and loop
straps.
181. Connect the fuel line to the carburetor. Make sure to use a
fuel fi lter to prevent debris from entering the engine.
182. Mount the fi ll line in the side of the fuselage using a fuel dot.
The overfl ow can be mounted on the bottom of the fuselage,
making sure it will not interfere with the cowling installation.
Route the lines as necessary.
 THROTTLE SERVO INSTALLATION
183. Install the grommets and eyelets in the servos. Follow any
instructions included with the servo. Install the servo in the
fuselage with the servo output facing the outside of the
fuselage. Make sure to prepare the holes as outlined in the
aileron servo installation section of this manual.
184. Mount the throttle servo connector in the throttle servo arm
so it is 7/16-inch (11mm) from the center of the servo arm.
Place a drop of canopy glue on the M2 nut, then install it on
the underside of the arm to secure the connector.
 It may be necessary to enlarge the hole in the
servo arm so the connector can rotate freely.
