Glow Engine, Fuel Tank & Radio Installation - GREAT PLANES SPITFIRE Instruction Manual

servo arm with a 5/64" [2mm] drill bit. Install a screw-lock
pushrod connector into the outer hole of each servo arm.
Tighten them to the servo arms with a 2mm flat washer, knurled
nut, and thread-locking compound. The nut should be snug
against the washer but still allow the pushrod connector to rotate
freely in the servo arm hole. Slide the pushrod wires through the
screw-lock pushrod connectors and attach the servo arms to the
servos (perpendicular to the servo case pointing out) using the
servo arm screws included with the servos. With the elevators
and rudder centered, thread a 3mm set screw with thread-
locking compound into the tops of the pushrod connectors and
tighten it against the pushrod wires. Cut away the excess
pushrod wires 1/4" [6mm] beyond the pushrod connectors.
Glow Engine, Fuel Tank & Radio Installation
The Combat Spitfire ARF is designed to be flown with a .25
glow engine or an out-runner brushless motor. If you plan to
install a brushless motor, skip this section as it only contains
information relevant to installing a glow engine.

1. Remove the stopper from the fuel tank and shake out
the contents.
❏
2. The fuel tank can be assembled as a two line system
consisting of a vent (pressure) line to the muffler and a carb line.
Filling and emptying of the tank would need to be done through
the carb line, or an optional fuel fill valve (not included). The tank
can also be assembled as a three line system having a vent line,
carb line, and fill line. If installing a fill line, puncture the third hole
in the top of the stopper above the sealed off fuel tube hole. The
fill and carb lines should extend out 1/2" [13mm] beyond the
stopper and the vent line should be bent upwards and left uncut.
With the tubes installed in the stopper, fit the stopper plates
loosely in place with the 3mm x 25mm phillips screw to hold the
assembly together.
❏
3. 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 clunk (fuel pickup) on the carb line should almost
reach the back of the tank but not touch. The clunk must be
able to move freely inside the tank when assembled. Adjust the
length of the fuel tubing accordingly. If you wish to use the fill
line to drain the tank, attach a length of fuel tubing and an
additional fuel clunk (not included) to the fill line inside the tank.
When satisfied, tighten the 3mm x 25mm screw in the stopper
to secure it in place (do not overtighten). Mark the side of the
tank that must face up when installed in the plane, and we also
suggest marking the tubes in the stopper.
❏
4. Insert the tank into the fuse with the correct side facing
up. The neck of the tank should pass through the hole in
the firewall.
❏
5. Cut a piece from the included 6mm x 6mm stick to fit
between the spars behind the fuel tank in order to secure
the tank in place as shown. When satisfied with the fit, use
CA to glue the stick in place.
