Fuel Tank Installation
Required Parts
Fuselage assembly Fuel tank
Hardwood tank support 1/4-inch (6mm) foam
Tools and Adhesives
Medium CA
 Step 1
Inspect the fuel tank so the lines inside the tank can be
identified. Note that the vent line in the tank will face to the
top of the fuselage when the fuel tank is installed.

 Step 2
Slide the fuel tank in the fuselage. Make sure to guide the
tubes through the hole in the firewall.
 Step 3
Cut the brace to length so it fits in the fuselage behind the
tank. Place a small piece of 1/4-inch (6mm) foam between
the brace and tank. Use medium CA to glue the brace in
position.

Drill bit: 1/16-inch (1.5mm), 5/32-inch (4mm)
Note : The motor shown installed in this section is the
Power 60. Installation of the Power 90 follows the same
procedure, but requires drilling the template in the
correct locations and the use of the 20mm Power 90
adapter placed between the firewall and the aluminum
standoffs.
 Step 1
Use a hobby knife with a #11 blade to remove the plywood
filler pieces from the sides, top and bottom of the engine
box. This will allow air to flow into the fuselage to cool the
batteries.
 Step 19
Use the radio system to move the throttle servo to the closed
position. Physically close the carburetor on the engine.
Make sure the direction of the servo and carburetor arm are
working in unison. Use a felt-tipped pen to mark the pushrod
where it crosses the outside hole of the servo arm.
 Step 20
Use the radio system to move the throttle servo to the full
throttle position. Move the carburetor to the full throttle
position. Check that the mark on the pushrod wire aligns
with the outer hole of the carburetor arm. If it is off only a
slight amount, you can use the ATV function of your radio
to correct. If the line is too far forward, attach the clevis to
a hole on the servo arm that is closer to the center of the
servo. If it doesn’t move far enough, use a servo arm that
allows you to position the clevis farther from the center of
the servo. Repeat the previous steps if necessary to achieve
the correct amount of throw to operate the throttle on your
engine.
 Step 21
Use pliers to make a 90 degree bend in the pushrod wire
where the mark was made in the previous steps.
 Step 22
Enlarge the hole in the servo arm that works properly for
the operation of your throttle with a pin drill and 5/64-inch
(2mm) drill bit. Secure the throttle pushrod to the servo
horn using a pushrod keeper. Use medium CA to glue the
plywood pushrod support to the fuselage in a position that
will provide smooth movement of the throttle pushrod.
